What size hull for my engine?

[Lubina]

Thanks again, very helpful.

Ill check out 20ft boats out there at the lower weight range.

Weight is very important.

Equally important is planing surface.

A true deep V will not get up on a plane, these are displacement vessels.
Typical Semi Deep Vee, like my Skipjack will get up on a plane with enough horse power to overcome the water I displace. I need about 3500 rpm to get up on plane fully loaded, then I can trim back to about 2500 or less & cruise. I can take on very rough seas with this design & ride pretty well. I have to have it .. bad back...

If the hull is flat, or nearly flat in the back, like a lot of Boats; Bayrunners, Pangas, & even some Parkers, the boat will plane very easily on less horse power, jump on a plane quickly, & burn less fuel.

So the lighter the better, & the flatter the planing surface, the easier it will be for your 90 to push a boat. Pangas & Bayrunners good choices. Maybe a bigger Bayrunner. A panga would probably be an excellent choice. Carolina Skiff, 18 Parker...

My friend had an awesome 18 x 8 Parker that could carry 4 guys, all there gear, bait etc, & did it with an 85 hp.

Good Luck

Thanks Nathan, really great information. I have my eye on a bigger bayrunner up north that would be perfect but it's a mess and way overpriced.

Some spray curtians, moving weight forward, Trim tabs, or even just a dole fin for the aluminum hull would prbably help if you don't have one already.

Be pretty odd to find another hull that just happened to need another tohatsu 90 IMO.

I don't understand your last comment jeff, what would be odd? You mean finding one with an existing tohatsu? If so i agree. My boat is already nose heavy and from what i have read trim tabs would not help make my ride anymore enjoyable.
