So I just got my restoration project in the water for the first time to test it out. Not so good, I can only get 6.4 mph out of her. here's some info-
'72 14'6" Tri-Hull
'86 Mercury 45hp classic 50
'89 Mariner 5hp kicker
I picked up the motor off a 20+ft pontoon boat and replaced the stator,trigger and rectifier since each had at least one wire the was a little burned, but it ran fine on muffs when I bought it (better safe than sorry). I tuned it up yesterday setting timming, linkage ect.
after I passed the no wake zone I slowly gace it some throttle but it bogged down real heavy after about 1/4 throttle and just got worse to full where i reached my max of 6.4 mph at 3700 rpm's. the really bad part was when I tested the 5hp kicker I got up to 6.6mph. THE WIFE WAS NOT IMPRESSED WITH THE 3 1/2 YEAR PROJECT!
I knew I would have a lot of tuning and weight transfer to get her running smoth but not this bad.
The help I really need is what prop should I start off with that will get me in the ballpark. I have no clue. The prop that is on now is a 9" pitch I think, it has 48-87818 A10 9P stamped on it.
The worse part is my boss is flying in later this week and is expecting a fishing trip since he gave me a few weeks off last year to work on it.
