Guys, please help!!
I currently live in Australia and need help with my Force 90hp.
If I haven’t made you close this window yet, this is my dilemma:
I have a 1992 90 HP force on a 17ft Fishing boat.
Boat is a deep 19 degree V, weighs around the 2400-2500LB ( attached a pic of the same hull )
I have rebuilt the motor, run it in and seems to be in very good tune of now. Everything on it has been cross checked and runs fine all the way to redline.
Problem is redline is 4000rpm and max's out around 50km/hr.
had a shipwright look at the mounts and the motor is perfect height on the transom.
I’m at a stage where the only thing left to explore is a prop swap.
Atm its running a 13.25 x 17P aluminium 3 blade standard Merc thru the hub prop.
Any ideas where my 1000rpm can be found?
edit ; Revs have been checked with snap on tool, and speed is GPS verified
