Got it. That was the plan. More because I was doing it outside the boat but I understand why you say go that way. Thanks

What hull is the 23' bottom from?

Matt,

It is a Tides which Venture boats later bought.

Joel,

Any idea what kind of force (thrust) a 90 hp motor puts out? I can dig in my brain cell to conver hp to thrust but I thought I would ask first.

It depends a lot on the engine, type, age, wear, it's RPMs, gear ratio, prop size and efficiency, and boat speed. Hard to say exactly without hooking it up to a scale, there aren't any easy and accurate formulas, but I'd guess roughly 1500 foot pounds, give or take a couple hundred.

Thanks Larry,

I remeber back in an aero propullsion class I took there was a conversion but that was for an engine moving air. I would think the design guides for boats might provide that?

[Matt Gent]

My best guess was ~2250lbs based on a few references at 25lb/hp for this type of boat, but it really is dependent upon a number of factors as mentioned above. It is not constant even for a given engine on a given boat across its performance/speed range.

Foot-pounds is a unit of torque or energy, thrust is in pounds.

Wanted to share some progress. Got the aft deck put together. The two small compartments at the transome will be baitwells/coolers. The larger compartments are storage which will be separated in the middle. The hatch gutters were made from the mold which I showed earlier and the hatches themselves were made from temporary melamine molds as well. The deck is cored with foam only because I have it.

Nice job on the hatches
