1994 Crusader Xli

i think you do have standard rotation engines. you say the cables are operating opposite to one another. some time in the boats life it has had new engines fitted and instead of using correct rotation they have switched the controls. you have one gearbox running in reverse to turn the rh prop the right way. i have heard of this before. it is a very bad way to run a velvet drive.

 

Have you owned the boat from new? Otherwise, someone might have changed the rotation of one engine. It is an easy test. Crank the engine, it doesn't need to start, and see which way the pulleys turn.

 

When I contacted crusader and gave them the serial numbers they stated that these were the original engines (granted its old enough that records were paper then).
I might try and confirm with via the transmission serial numbers as well.
I am the second owner of the boat.

 

Why don't you do what gonzo suggested and wind the motors over. See if they both turn the same way. I still think 1 gearbox is being run in reverse. You only have to hit the key to find out.

 

well all of this is getting a little off topic from my original question which was:

I believe these motors to be Gen 5. Does anyone know the power curve and cam profile for these motors? Additionally will the the TBI and intake on my existing motors bolt up to a Gen 6 long block?

I am trying to either find a reputable company for either new or reconditioned long blocks. So if anyone has recommendation suggestions I would be very grateful. It appear that replacement engines are long gone but it there is some new old stock somewhere ...... The only other opinion I can think of is finding a quality machine shop.

The boat is on the chesapeake bay right now.

 

You need to know what rotation both engines are so you can see if 1 of your gearbox is running in reverse. If you come here for help and don't accept it you might as well.not worry about posting questions. Why are you so against doing a simple test to confirm rotation. What are gearbox numbers going to tell you. All bw 1.5/1 are standard rotation so that will tell you nothing.

 

Yes, I am asking for advice but my questions are the following:
- if a 7.4 Gen VI long block with work a Gen V intake manifold and throttle body injection (i am aware they did not make counter rotating Gen VI)
[since it appears new block for the Gen VI are available]

- data on 1994 Crusader 7.4 XL (with throttle body injection) such as hp/torque curve, cam profile, cylinder head type
[if I get with recon'd long blocks I want confirm that I get the same set up as I currently have

- recommendation for quality and honest machine shops / mechanic around the chesapeake bay


The boat is current located a few hours away from where i am, but i am confident they are standard rotation:
- according to Crusader records when I gave them the serial numbers
- according to LH plate on the engine
- by looking at the shifter connection on the transmission

 

No

Not being near the boat does make it hard to check. You either have 2 lh props or a gearbox setup wrong. Good luck. Hope you get it sorted out.

 

Just for clarification this isn't a stern drive boat - props are 18 X 21 X 3 blade nibral

It's the original set up, which lasted over 20 years and almost 2000 hour of use

I don't have enough knowledge to say if this is the ideal set-up but i am happy to repeat those results again

 

i realise they are shaft drives. when you said the shift cables were opposite is what makes me think 1 gearbox is running in reverse and it is something you should rectify. they do work like that for a long time without much load. if i am wrong thats fine but it must be looked at.
