Re: PROP or ENGINE SHAKE???? above 4,000rpm

If you don't find something more accessible and/or obvious, I would suspect your flexplate is cracked/cracking. Exactly the symptom(s) you might expect to result from such an issue. Bearings in the drive going bad could possibly lead to similar symptoms. It is worthy to note running a bad flexplate ...

Are your attempts to contact them through or at Dyna Marine ? If not, maybe these numbers will afford you better results ? By all means send that sucker in and we'd be glad to take a look at it and see if it's a gear issue or what. Give me a shout any time and I'd be glad to help! Shane direct: 785....

Re: Destroyed my prop

They do still make the S blades as far as I know. Did that one blade take the brunt of it? If the other two aren't damaged, I would expect you could send them to Sensenich and have them balance a set with a new blade. If your performance was not what you think it might have been, you won't get a bet...

This ideally should have been much higher in the thread, but I don't think I saw it mentioned. However unlikely it may seem, it may be beneficial to confirm beyond a doubt that your fuel tank pick up does not have some kind of obstruction. Most have some type of filter, I've seen more than one wreak...

If I remember correctly (and chances are better than fair that I don't), the OP did not pursue this, for justifiable reasons. Of course, it's possible that he did and I'm simply unaware of it, although I doubt that to be the case. This has been done here and elsewhere, but results in more of a novel...

Holley carbs are designed to run 7 - 7.5 psi. Going beyond this can cause other problems. Accord to the following link, the Red Holley will put out 7 psi and would not require an additional regulator. The Blue Holley puts out 9 psi and would in fact, require a regulator. https://www.holley.com/produ...

Re: HELP! Belt Drive Knocking Noise

Not exactly clear on which you are calling a flywheel. Typically you would have a flexplate plate bolted on the crank, and a drive plate mounted on the reduction. Do you literally have a flywheel on the crank instead of a flexplate? Could be a lot of unneeded mass to spin up. In any case, if those t...
