Those of you running a 300 series with no jackplate, what hole is your engine mounted on? Also what is your setup....boat, engine and prop?
Im trying to setup a friends 373 with an Evinrude 150XP. We are chasing our tail on this setup. I feel that the engine is mounted too high and the props are just slipping and he has tach issues.
We've run a Michigan 3 blade 13 7/8 x 23, Trophy 23", Powertech RKR 25" and a Shooter 27"
The performance of the props that I feel should have been correct were horrible on every level. He says that the 27 Shooter gave him the best topend with an almost instant holeshot!?!?!
His engine is mounted all the way up and a quick check of P2P has it about 4 1/2ish BTP. I didn't have much time to mess with it but I think that the larger props were working well because the prop is slipping so much and they were providing enough bite for it to appear to work better.
I wish his tach was working properly but every prop we ran that day the boat barely broke 50MPH.
Let me know what you think.
Thanks!
