What hp on your 20

Welcome to the madness here...

Check out the PIC of my boat with the Yamaha 225. It does ride a lot lower in the stern, I have to shift weight up front to even it out, if everyone walks to the back the scuppers go under.....

Reworked 1983 20cc w/t-top 200Merc 2.4 liter carb on bracket 17p 47.9 on GPS. Not concerned about weight. Scuppers were done away with. No longer a self bailer. Just finished this 10-year project and hope to repower with a 250 3-liter in the fall.

The weight of the 225 certainly contributes to her sitting low in the stern, but it does seem to be a problem for a number of the V20's even with 150's on them...

A 150 two or even a four stroke should not be any trouble scupper wise, unless you have excessive weight in the back, or saturated wood or some other abnormality.
On the end of a bracket it would likely be a problem though.
All of them will bob and weave in a sea drifting with the scuppers being dunked, that is normal.
But making them non self bailing seems odd to me. Unless you have arranged some super double bildge pump arrangement to compensate for it.
The need for speed can be compelling I guess.

Speed wasn't the reason. The extensive redesign with the motor bracket gave me another 6 sq.ft of useable deck space. Because we were unsure of the at rest water level with a full transom and the bracket we omitted the scupper holes. I have the double automatic bilge pumps as you mentioned. Shifted a lot of weight forward in the boat to compensate for the bracket and the results were awesome. At rest we could put the scuppers back in but I hate having water on deck when heavily loaded.
That is what you risk when you modify the original.

Havent got it in the water yet but the project boat I got has the mercruiser 470 I/O which I beleive is a 170 HP motor. Does anyone have any specs on that motor and speeds?
