Re: Classic 1963 21 Video and pics
Congratulations on your successful sea trial Brian! Looks like that motor is plenty of power! That bracket is probably worth 2-3 mph and it sounds like you could pick up another few mph with a lower pitch prop. What is bracket setback and how far is cav plate above the hull? Mine is 3.25" above bottom, with a 30" setback. I kept raising motor and gaining speed until I noticed I had to trim motor down more to keep it from porposing, but I can still make hard turns without any ventilation. You might want to try an aluminum prop until you get it really dialed in with normal operating load. A good quality aluminum prop can be repitched until you get it where you want it, and then you'll have a better shot at getting it right when you spend big bucks on a SS wheel.
You're right that it does look light - it looks like the chine is just barely wet at the transom! It also seemed to be bouncing off the waves more like I'd expect from a 20; don't remember the Unohu having that much motion in small waves or having that much bow rise coming on plane, but I'm sure it was quite a bit heavier, and being a sterndrive, the CG was quite a bit further forward. That said, you won't find a better riding hull that size! Maybe you need to rig one of the patented Moesly ballast tanks in the bow!
Terry, Bob said the Unohu was a 50 mph boat with the last engine he had, which was a 270 hp/350 ci Chev/Volvo sterndrive. You should also be quite a bit lighter without those big molded fg seats, so you'd better have a kill switch lanyard attached to you the first time you nail the throttle on that rig! Denny
