[QUOTE="CedarRiverScooter, post: 457189, member: 15465"] Tig is too tedious for me, I just use it to fix the porosity. Does your donor ski have power trim? if so, great. The big issue I ran into with my last engine install was pump angle. It is too high & boat porpoises over 30 mph. I finally resorted to trim tabs after trying lesser remedies. Trim tabs are working OK. If you don't have a way to adjust trim, you may want to have a way to easily shim pump angle. I don't think even trig will predict planing behaviour of a custom hull.
