Re: Apache hull

Conventional wisdom (and the Fla law mandate) says that it should be on the outside of the transom, on the
starboard side and near the top. If you can't/don't find it there, maybe the hull was cut down and it's now MIA.

Re: LOW TORQUE LS Engine Build

Sorry Mr. Gator, but this time the nod goes to the Diggin' Fool. Yes, I do in fact dispute your graph, in spite of your misconception of it 'simplifying things'. 1) Torque is a measurement of rotational force, (Ft/Lbs). PERIOD. 2) The formula for determination of HP, is calculated by taking the firs...

You have a good option in left field that you had not shared prior to your last post. Unfortunately, the Laws of Physics don't play favorites or accommodate good intentions. EVER.

Re: 0320 or 0360

It is likely that case number is a casting number rather than a serial or part number, so may be of little use. I can't help with the type of measurement you're asking about, but I'd think if you were to measure the stroke, that would provide another clue if not provide the answer you're after. An O...

Re: 9hp single seater prototype update pics

Initial reaction is to say "Make sure his life insurance is all paid up." Even nine HP w/prop is enough to kill you if it hits you in the back of the head. I know that is not helpful, but in all fairness to anybody that might respond, you need to supply more information and/or pictures. En...

Re: anyone running a 350 with 2.1 box?

500lbft/ 400hp turns way way less prop and makes way less thrust than 400lbft/500hp Ultimately, this statement is a demonstrably true fact without a doubt, (provided that the definition of "way way less prop" is admittedly a subjective observation). According to my AC pocket protected fuz...

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 ...

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...

If I remember correctly (and chances are better than fair that I don't), the OP did not pursue this, for justifiable reasons.
