I have a 2005 Nitro 901 CDX dual console
It has a 150 Efi Mercury serial # 0G803380
21 pitch Tempest
Rpm- 5000 or so.
Speed- 50 mph with just me and my gear.
48 mph with 2 people and gear.
My question is what could be killing my performance ?
This isnt the first engine I've had on this boat and they have all run slower than what I figure they should.
The engine seems to be fine.
Compression on all 6 cylinders are between 110-115 psi
I know this is a heavy boat and the performance will be poor with that little 150 merc. I just figured it should do better than this.
Thanks guys
