    Sending unit and Moeller Fuel Sending Unit Conversion Capsule

    I posted this problem in the fuel section but got no help, maybe someone may have some suggestions in this Crusader thread. I installed a new Moeller fuel sending unit, which is different than the previous sending unit that was installed. This previous unit was the sending unit with a Moeller...

    Sending unit and Moeller Fuel Sending Unit Conversion Capsule

    I installed a new moeller sending unit, which is different than the previous sending unit that was installed. This previous unit was the sending unit with a Moeller Fuel Sending Unit Conversion Capsule. Two wires went to the Moeller Fuel Sending Unit Conversion Capsule and two other wires were...

    Spark Plug Wires

    I searched the forum for info regarding the best spark plug wires to use because i want to replace the wires on my 89' 7.4 I read some are using automotive and not paying the higher price for marine grade wires. Can anyone advise as to which wires to use and where to get them?

    Engine painting (Ospho)

    When I was changing the spark plugs I noticed a lot of rust on the lower block on both engines, out of sight unless you are very low. A friend told me about Ospho and I just read some info about using it. What I an thinking is to brush off as much rust as I can, then apply Ospho with a rag or...

    Engine harness 89' 454s

    Just a follow up, some may remember that I was tackling the tach and sync gauge issue of not being accurate. Friday I finally got around to disconnecting the engine harness plugs at the rear of the engine. Cleaned the corrosion off and sprayed with electronic cleaner, but ran out so I used...

    Low voltage partially solved & sync gauge now more accurate

    I had another mystery with the boat last week. I decided to equalize my batteries, I did it last year before I added 2 additional batteries and it worked fine, Pronautic 1250 (3 bank, 50AMP Charger). This time when I set the charger to equalize I did not know I was going to have problems. I...

    Low voltage

    Not sure where to begin with this problem. I have two blowers, when they are on the voltage meter reads low (forgot the volts) but it is low. My instrument lights in the dash panel are low too, making it difficult to read them at night. This problem has been going on for a while and I figure it...

    1989 7.4 Crusader wiring harness

    Today I attempted to disconnect the wiring harness plug to clean them on both engines. It is really difficult to pull apart, so before getting myself into trouble, I thought I should ask how to take it apart. My concern is a snap type piece of plastic that I do not see and I may break it. I have...

    Sync Gauge + Tachs

    Now my alternator problem is fixed, I want to figure out how to get the sync gauge and tachs in agreement. I have been reading as much info as i could find and there is not much I can use at this point. Most posters to other forums state they rely on the sync gauge and not the tachs. I have been...

    Alternator wired direct to the battery

    The other day I read a post and one person stated there is a improvement when alternator is wired direct to the battery and not the starter. I have low voltage on my starboard engine volt gauge, the analog meter on the main DC panel shows a bit over 13 volts, the same voltage as the port...

    Port exhaust Louder than Starboard

    On my 89' 454's the starboard engine exhaust is very quiet. The port side is much louder and the water has more a spray to it than the other side. I am sure this is not my imagination :-)) The reason I started observing this was my generator trips a circuit breaker which I believe is due to a...

    Grounding Thru-Hulls

    I understand this is not a Crusader question, but you all have great knowledge, this is the best place to ask. I am replacing a broken plastic thru-hull fitting with a stainless one. On the new fitting there is a screw which I assume is for grounding. Is it really necessary to ground this one...

    Aluminum versus Cast Iron

    Getting ready for my next project, exhaust manifolds and risers. Time to get rid of the log style manifolds. These Aluminum manifolds may offer some benefits such as a weight reduction, but can they handle the heat? What is the general opinion of these: Complete Aluminum Kits – only 35% the...

    7.4 water pump suggestions

    My port engine has a squealing noise, at first I thought it was the belt. After inspection it appears to be the water pump. My question who makes the best water pump. Crusader OE is around $155, versus Sierra at around $130. Not a big difference in price, which pump is better? Any other...

    "I found this on another forum "I found this on another forum and thought you guys would find it interesting. This research was conducted by engineers, so I personally believe the results. Especially considering the fact I find PB Blaster to be not as good as I heard." Here's the summary of...
