Stalls when shifting into FWD

WSNW - don't look too hard for a problem that is not there... Not operating an engine at temperature can have all kinds of different performance effects.   get your thermostat in, and see if that corrects the issues you are having.   Summer is coming!...   supposed to hit 70 this next week    

OK. I didn't realize no t-stat would cause that noticeable of a problem.

Help me out, how does the lack of a thermostat cause a problem shifting into fwd?

Likely a vacuum leak or too lean air/fuel idle mixture. Start tuning and buy a cheap vacuum gauge. Vacuum should be at least 15 inches idling in gear pushing against the trailer. Also, check initial ignition timing. Retarded timing can make it lazy at idle.

Well, Cool Hand hasn't logged in since Dec 2 2010 so I don't think you'll be getting an answer from him.

I think I'd start by looking at making sure the throttle and shift cable and carb are adjusted correctly before assuming that an out of alignment shaft will cause your problem.

It's gonna be out of alignment whether it's turning frontwards or backwards.

You didn't mention whether you have a tough to turn shaft.in your boat.

Being an 89 You would have a PCM transmission with a 1:23 to 1 fwd ratio and about a 1.8 to 1 reverse ratio but the slightly higher load due to the gearing difference when you put it in fwd is not the problem unless you have tuneup issues or like mentioned earlier, cable adjustment problems.

figure the boat is 18 years old and probably never aligned, I think you'll be surprised

definetely looks like you need to work on the alligment..

Throw some water on the strut bearing and you should be able to rotate it with one finger.

Define easily? Should I be able to spin it and how many rotations should it spin if I were to try and give it a wing?

Maybe i could get a turnover resistance using a small torque wrench. Havent checked, will try and check tonight.

Update
Boat ran and did not sink. Not sure the packing nut is exactly right, but its good enough for now, though there is a bit of a story to tell with that. I'll print off a tutorial and set it up again for good measure next time out.

I think the carb, while needing some adjustment and a good cleanup up is fine. I still think theres something lugging the drivetrain in FWD. When it engages is drags the engine down 750 to 1000 rpms causing a need for a 1200-1400 idle. We did this and it worked good enough all week (read not stalling on every engagement).

Thanks to chris for stopping by and giving me the newbie once thru on nautique as I've still got a lot to learn.

Now I got to get caught up on work here.

Hope his vacation is goin well..

Great job Chris, on going to help him get her running.

that is just sick in so many ways.


But What I found yesterday was, a loose, cable on the new battery install, a loose spark plug, and several loose carb bolts, and throttle cable adjustment issues as well.

So what I feel was the main issue and I hope I corrected the issue since we didn't water test it, but the cable adjustment being off actuall was pulling it off the idle curcuit and I think there might be some varness on one mixture curcuit, so I made some adjustment to the carb and linkage and hope all is well.

I pointed out a couple things for him to check and adjust once he's on the water so hopefully they no issues on vacation.

Notice I said "dealer"?

Might wanna have a camera handy and post some pics of the gathering!!!
CCF members meeting to help each other are way cool...

Ok, got a hold of chris. You guys are great!!
