porposing bow issue??

[seapuppy]

you need to have the alignment checked...if the engine and drive isn't pretty much straight..it will vibrate....

I also have an '06 2600SE, and I've noticed vibration at times. The first time I thought it was a helicopter overhead! It's happened a few times and seems to go away on its own. Now I'm wondering if I need to have it looked at by a mechanic. Is a U-Joint a big $$$ job? Something I need to get fixed immediately, or can I let it ride for awhile?

the way to tell if your u-joint is going out is to crank it over in a hard turn....all the way over...if your hear growling or noise in the back of the engine only in turns..it's a u-joint.....bout the only thing to do is pull the drive and replace the u-joint....it's not a hard job and will only take about 2 hrs to do with a good mechanic....


parts are about 50 bucks and the time for the mechanic to pull the drive..take the old one out and stick the new one in...a little beating and cohersion maybe needed but it doesn't take long..

Thanks SP, I'll try that next time we're out. Do we need to be at planing speed, or is displacement speed good enough to hear the noise?

Didn't see your note about alignment earlier, guess I can have that checked. I'm hoping I can wait until the off season.

Thanks SP, it does not make any noise or have any perceivable vibration at full turns under power. Only when I trim up too much. I did check the length of the rams the last time I had it on the trailer and they were dead on spec. I would estimate that the vibration starts about half way to the limit stop.

Thought that was the test for the gimbal bearing Steve?

[seapuppy]

nope...gimble bearings give a growling noise that gets worse in a turn at slow speeds....you can always tell a gimble bearing is going out when it starts to growl...

ps...I found out the hard way that mine were going out.....

thanks for all your suggestions, i found the fix. well at least for my 2900se, before i accelerate from idle i lower the trim tabs 5-6 indicator lights. once i am up on plane i have a lot more ability to raise the bow using the engine trim with out the bow porpoising .
