Remote Oil Filter Kit Recommendations

My boat is a 2000 Crownline 205BR with 5.0L Mercruiser Alpha One - Gen2. I'm looking for recommendations for a good, moderately priced remote oil filter kit for this engine and would appreciate your suggestions.

As I winterized this fall and changed my engine oil I was reminded how much I despise the process of changing the oil filter. The acrobatics, yoga, and contortionist positions it takes to change the filter without spilling oil in the hull is on a level that this 55 year old body just doesn't like anymore. Each of the last several years I've told myself to install a remote oil filter during the winter......and every year the time gets away from me. I have now promised myself THIS IS THE YEAR!

I don't have my engine serial number, but Part # 807459A09 - Remote Oil Kit appears to be the right item for my engine. I support MarineEngine.com in every way I can, but $445 seems very steep for some hoses and fittings. If the OEM kit is the best option, then I'll bit the bullet but I'd sure like to spend about $200 or less on the parts.

Fire away with your suggestions and thanks in advance.

this is the one I wish I had bought when I did my repower, I curse not doing it every fall when Im hanging upside down filling the bilge with oil. You will find some cheaper ones but this one has swaged hoses vs the generic kits you see for automotive applications with hose clamps. Being its from Marine Power it is an OEM quality system

marineenginedepot.com

5.0L - 5.7L Remote Oil Filter Kit

Remote oil filter kit for increased serviceability. Mounts on Mercruiser (1983 and up) and Marine Power center rise exhaust manifold systems. Bracket may need modification for use on other brands. Includes Oil Filter, Bracket with Fittings, and High Pressure Oil Hoses with Fittings.
marineenginedepot.com marineenginedepot.com

if you haven't tried it I cut off a gallon jug , put that in the bilge and then drop the filter into it... that has kept me from putting the remote on for ten years.

Also you may need to change out the bypass spring on the block filter adapter for a higher pressure one, seems to be conflicting advice on if you need a higher pressure bypass.

That kit looks good but it's showing out of stock everywhere I look. I definitely want to avoid the hose clamp style and prefer the swaged fittings.

I've used a quart side plastic pail under the filter for a long time and that works well. But trying to use one hand on the pail and one to unscrew the filter in that tight space is just getting harder each year.
 
As someone who has changed the oil in boats more than 1000 times, it's one of the reasons for my opinion that anyone who designs boats should be required to service them for at least one year. A filter relocation kit takes very little space at the top of the engine and because the space around boat engines can't be too tight, it's really a no-brainer, but only if they gave a rat's butt about making their boats serviceable. I don't mind the need for special tools as much as inaccessible parts.

Didn't realize it was out of stock. You could try reaching out to Michigan Motorz. They used to sell it with their crate engines, so maybe they carry it and will sell it separately.

Alternatively if you can find the two housings you can go to a place that makes hydraulic hoses (forklift repair shops too) and have your own hoses made the exact length for your boat. the summit kit below fits SBC and is relatively affordable. You can toss the hoses that come with it out and get your own made.

Yep, same here getting too old for this ****... I think it was a $200 upgrade when I bought my partial engine from Mich Motorz back in 2015. kicked myself for not doing it then...

Precisely! The engineers should be taken to task for thinking its fine to contort your body into a small engine compartment to reach down into the bilge and remove a filter without making a terrible mess. Remote filter kits should be standard on any inboard engine.
 
I called Michigan Motorz and ordered the same kit they sell on their turn key engines. Price wasn’t bad for what it is. Still haven’t installed it but might this fall.
 
On this topic one question that I couldn’t get a straight answer to was the bypass valve in the filter base in the engine. Sone say it should be changed from the standard one (11 psi I think) to a higher psi one (30 psi) to prevent oil from by passing the filter due to the added restriction of the oil hoses. Not sure if this is an issue or not. On the V8 it’s easier because you can pull that adapter and knock out the valve & stake in the higher pressure one. Not easy on the 4.3 because it’s staked into the actual oil filter pad on the engine. I don’t think I have good enough access not to bugger up this job. Hence why it’s still in the box lol! My oil filter access is tolerable but it would be nice for sure to have it….

Granted, I'm a Clydesdale, but I have worked with smaller service techs and they had access problems, too. I have a friend who has worked on boats, too- I commented on how difficult some tasks are and he said that he didn't think most were too bad and I said "OK, Rinker 19' open bow, oil change". His reply is hard to spell, but it would be similar to gagging. Too low, no access hole from the side. I have ape arms and it was still hard for me- if I had dropped the filter, it would have stayed in the bilge.

I have to think that someone who cares more that they have the kit is more important than where it came from could go to a boneyard and remove the parts (fitting at the filter for the oil cooler and hoses to the radiator) and if they find the remote filter mount, buy that, too. Plenty of shops can install new ends on the hoses if they don't fit the remote filter mount. Should be much less than $450.

I juist checked and NAPA has these parts at $135, Autozone is at $119. Add hoses and some time- done.

Well guys, my search is over and it looks like I need to either just deal with the OEM filter location, make a Mercruiser kit from a different year fit, or use a generic system remote oil kit (with or without manufactured fittings on the hoses). I emailed Marineengine.com and other parts suppliers and got the same answer from them all: for Mercruiser Engine Serial # OL689804, Mercury will only let them sell the parts individually, they are not given a complete kit to sell. There's no way I would buy the parts individually because it would total over $600 to make that happen.

I emailed Michigan Motors asking if they would sell their kit separately from a long block and got no response.
 
I would call them they did sell me their kit but it took a while for them to get all the parts together. Price wasn’t bad.

What is/was the Mercruiser oil filter kit part number that should fit your engine model you had been looking for/told to use?

Often you could be able to possibly find something say slightly cheaper? that fits either by searching the OEM part number or typing in Merc oil filter kit (or etc. for other items) and either find something new or used even.

A linked example below though in reading it’s full description suggests it fits the next model year/serial number range up from your 0L starting number… 2001+, thus the reason to compare your kit number needed.

So here's the funny thing, when I enter my serial number and look for the Remote Oil Filter parts page it only shows me individual components, not a complete kit. That is why I emailed Marineengine.com and other suppliers asking specifically for a kit catalog number to match my engine serial number and every one of them said, nope, no kit for that engine, only components.

But, you are right that Kit # 807459A09 does have the following information in the description " Fits 1997‑2002 MCM V‑8 (305 & 350 cid) carb engines with standard cooling (s/n 0K001501‑0M614999)." This certainly sounds like my exact engine, so I'm not sure why the kit does not show up on the parts page for my serial #.

I've done a lot of general searching and I have found used units, but I don't feel comfortable putting used hoses on my engine's oil system hoping that a stranger has sold me parts that don't leak.
 
Remote oil filter mount for 4.3 V6.jpg

Here's the one Michigan Motorz sold me for my 4.3, it's the same one they use on their turn key engines, set up so the bracket bolts to the OMC/Volvo style exhaust I have on it. Like I said, I didn't install it due to concerns about the bypass valve in the block which on a 4.3 is very difficult to change with the engine in the boat. What I thought of doing, which might be one way to tell if the oil bypasses the filter, is this.
Run the engine on the water hose for a set time interval, like a half hr to 45 min. Then take a temp reading on the OEM oil filter in the stock location. Then install the kit and do the same thing, if the temp of the oil filter is about the same, that would suggest to me that oil not bypassing the filter. If the oil filter is cold on the other hand, it would suggest that the bypass in the block opened and the oil is bypassing the filter. I'm using Merc/Quicksilver syn blend 25/50.
Since this fall I am going to replace the exhaust (will be used in salt water for 7 seasons by then, so it likely will be due) I will have good access to that part of the engine. Normally when I winterize this boat I have to move the rear seats out and remove the wood partitions that support the full size sun pad. It's getting old for me at 70 years old. Ideally my next engine will have closed cooling and the remote oil filter. 2 things that make owning an I/O tolerable. The thing is I still have to get in there to get at the drain plugs anyway. I thought of a way to make my own quick drain system but I'm concerned it might clog and not drain. No way to know except to measure what comes out of the engine! I have always manually drained and poked the holes, most years it's not clogged but it has happened.
I think the set up that MM sold me is a good one, it looks well made all around.
Honestly the remote filter system is something that has to be top quality, a failure will destroy an engine in minutes. So paying more for the best system you can get is the only way I'd do it.

that is the Marine Power one that has been out of stock for a long time. Best way to replicate would be to buy the adapters for block and filter (or kit like NAPA unit above and toss the hoses )and have a hydraulic shop make hoses. Any place that makes hydraulic hoses or does forklift repairs can make the hoses same as you the MP kit.
 
I called a few places and checked some websites- oil lines with crimped on ends cost less than $30 each, so if the other parts can be sourced, it would cost less than a kit.

Thats the way to go then. I would have thought the hoses would be more.

A good and thorough flushing would be good enough.

when I purchased my 1987 350 V8 boat in 1995 the first thing I did was to install a remote oil filter so I did not have to hang upside down to change the filter.
I purchased the two adapters as seen in all the images and had the hoses made all at NAPA. It looked pretty much like post 17.

This year I replaced the hoses and fitting as the hoses outer covering was peeling off after ~ 30 yrs in use.

I replaced it all with AN-10 hardware (fittings) and hose for oils systems, all from one source. See image for AN parts and prices. Now it is even more serviceable as the hose which I purchased enough for two sets and the fittings on the hoses are reusable if need be.

So if you purchase the two adapters, Make your own mounting bracket for oil filter side (Which I did) and buy the items below you can make your own as I did and am redoing.
The hose is 10 feet long and I cut to fit my needs.
If you dont have the skills to do so or prefer not to do all this work, then purchase a complete system and clean well and clean well again until very clean, Replace any o-rings and you should be fine.

You could look for a range of kits from parts stores, toss the hoses and order new hoses with crimped ends for a lot less than $200
 
Just for information that mount in the kit that I bought from MM, was made by Canton Racing, you can find it on their website.
