"Hi. Long time reader, first t

"Hi. Long time reader, first time poster. Anyway got a few questions that I have seen hit on here and there on the forum.

Engine is a 1963 Evinrude Starflite V 75 HP

First off, I just ran across a thread that states that a 50:1 fuel oil mixture can safely be used in this engine. Can I get some confirmation of that? The placard under the cover says to use a 24:1 ratio, but given the changes in oil in the 46 years since the engine was built, it kinda makes sense and really makes me curious.

Second, has anyone successfully fabricated some sort of trim tab for this engine? The torque makes the boat wand to turn hard right.

Finally, this is more of an answer to a few other posts I've seen about the charging system on these engines and how to make them work. I fixed mine by grounding one side of the field coil and using a NAPA VR32SB voltage regulator ($16.00.) Once adjusted properly it will charge the battery like a champ!

Got several more questions, but I'll leave it at that for now. ;)

Thanks"
 
"The bearing setup within the

"The bearing setup within the powerhead of that engine makes it compatible with the 50/1 mixture.

The 24/1 mixture was the common OMC recommended mixture many years back BUT that was before the 50/1 TCW-III existed.

Trim tab? Not that I'm aware of.

Thousands of parts in my remaining stock. Not able to list them all. Let me know what you need and I'll look it up for you. Visit my eBay store at:

Awesome! Thanks! That will be

Awesome! Thanks! That will be a nice help. Much less smoke and mess. ;)

I'm working on a trim tab setup and will post back as to the results..just wondered if there was something tried and true out there..
 
The trim tab experiment thing

The trim tab experiment thing will be interesting. Keep us informed.

It sticks in my mind that there was some kind of brake/tension setup at the swivel bracket area to prevent the free swinging problem such as the smaller hp engines have but I may be mistaken. Hard to remember back that far.

Now for another question. How do you determine correct prop pitch? current prop is a 10¼x10 and boat has trouble getting up on plane with a full load. I have found 10x11 and 10x12 props available, but would this help?"
 
"There is what is called a pow

"There is what is called a power propeller dsigned especially for the older V4 engines that makes the engine eprform like you installed another engine along side of it.

The diameter is about the same BUT the hub is smaller giving it more blade area. The dia and pitch is 10x9-1/4 and I believe the part number is 379260 which probably is no longer available but many of these propellers are still around. This prop will have your rig jumping out of the hole and on plane.

Check with Andrew (host & owner) on this site. Perhaps he has this prop available.

"Thank you again! I happened t

"Thank you again! I happened to catch your post just before heading out with it today and happened to have one of those props in the garage. I reinstalled it and tried it out. Man what a difference! Out of the hole quick and 5 mph faster! It was on the boat when I got it, but it was (and still somewhat is) in really poor shape. I replaced it during restoration with one I acquired with a replacement gearcase assy for the engine. A newer/better one is still definitely in order since it is so beat up though.

Also somehow this fixed the trim tab issue as the boat no longer yanks to the right.

Great...... the performance of

Great...... the performance of those power props is something that many wouldn't believe. One simply has to experience it.

"Well..it is with great sorrow that I must announce that this engine died today..

During starting I noticed one cylinder had slightly weak compression, but the engine fired off and ran fine so I thought little of it. About 2 hrs later it stalled. Thinking it was just water in the fuel (we'd just changed tanks) i attempted to restart but found that it was seized. After a brief cool down it freed up and started again. Ran good for about 2 min and did it again (I had no choice but to run it again as I was way out in the middle of the lake 15 miles from the trailer.) Got it going one more time and ended up idling to the nearest boat ramp..still 15 miles from the trailer.

So, finally after getting it to shore, getting a ride back to the truck, going back and loading up, and getting it back home...I started investigating the issue. The #3 piston appears to have had it's connecting pin come loose or something to that nature. There are 2 deep and wide (about 1/4-1/2") gouges in the cylinder wall one on top and one on the bottom. The other 3 cylinders look fine.

So..unless there are any good suggestions, I guess this old engine has had it's last day out.

Sorry for the long winded post.."
 
"Damage of that nature could o

"Damage of that nature could only result from a wrist pin riding up and down within the piston, riding against the cylinder wall.

However, I have never heard of having both wrist pin retainers fail which need to be the case. It sounds more like someone neglected to install those retainers.

If you decide to keep the engine, then obviously a major overhaul is required. This would necessitate having that damaged cylinder resleeved, if possible.

Cylinder sleeve for that model? You would need to check with a machine shop for the answer to that."
 
"Wrist pin..I racked my brain

"Wrist pin..I racked my brain last night trying to remember what that thing was called! lol..guess I was just too tired.

Anyway..I was wondering about that..whether the cylinder had a sleeve or not, or whether one could be installed.. I guess I'll tear it down all the way and take it around to see what the machine shops say. If they can do it, surely it'd still be alot cheaper than a new engine.

Will keep ya posted on what I find out..and thanks again!"
 
"You might advertise for a par

"You might advertise for a parts motor. The last motor I had sleeved was $100 and that was years ago then the piston was $60. so you should have better luck shopping for a parts motor--might even try the repair places, If they are like me I never threw anything away if it was shiney.

And have to agree --I never heard of 2 wrist pins fail at the same time less they had those nylon buttons in them and severly overheated."
 
"I know of a place nearby that

"I know of a place nearby that has one of these engines. It is lying on the ground and missing a few parts (namely the lower unit as I bought that a while back.) I have no idea of it's internal condition, but might be worth looking into.

Also I have a friend with a friend who runs a machine shop..he doesn't seem to think it would be very costly to resleeve, but we'll see.."
 
"Resleeving thru a dealership

"Resleeving thru a dealership is costly due to overhead. However, resleeving directly thru a machine shop is about $40.00, possibly less. Check around a few machine shops and let us know what they say."
 
"Well..I have the power head o

"Well..I have the power head off, but not apart yet. Hopefully that'll be tomorrow's project. Got to wondering about something I will definitely need, though,..gaskets. After seemingly endless searching on the net with no success..where can I get a set of these? Will I need to make my own? I have a service manual on order, but wondering if someone might have a good P/n handy so I could get a gasket set on the way too. I found the head gaskets, but it is all the rest that I am concerned with. I found a 388602 gasket set, but it is for a later model (1970's) 85hp engine..will it work?"
 
"You'll probably need to p

"You'll probably need to purchase the gaskets separately but they should be hard to find.

The 1970 gasket set is quite different, won't work.

Your powerhead was basically the same design up thru 1968.

"Well..latest update.. Cost es

"Well..latest update.. Cost estimate for a resleeve is $300..that includes no parts except the sleeve. They said it is $100 to resleeve, but has to be sent off to have the intake/exhaust holes bored and the last one they had done ran $200 for that.

I know a local boat salvage yard that has/had one of these engines. I don't know what condition it is in, but if it is ok internally I might can go that route. If nothing else I might be able to get some needed parts out of it or even frankenstein the 2 together to make 1 working unit. LOL

As to the initial cause of the failure, it was indeed the wrist pin. 1 of the 2 snap rings failed. Apparently a piece passed through the pin (it is hollow) and got lodged on the other end resulting in the grooves worn on both ends. Also found another piston on the verge of failure. The wrist pin was loose (the hole worn) and a piece of the piston had chipped off around the hole. No damage to the cylinder though.."
