I am to purchase a Brig Navigator 485, rated for 75HP
I want to put the Yam 75 on it but some people and my dealer told me the added weight of the engine will not enhance the performance so much.
The 75HP is double the displacement of the 70Hp. Some people who had the chance to try both engine on their fishing boat say the 75HP is alot better performance wise. But its fishing boat, maybe its different for a RIB??
My friend got a Bayrunner 500 last year with a 70hp and i was not fully impressed by the hole shot and the Brig is heavier than the Bayrunner
Any helpful hint on this?? Maybe in the 1.8 liter, the difference is bigger if you choose the 90 hp, not so much the 75??

1st rule of outboards “there is no replacement for displacement”
Don’t get seduced by HP, torque is your friend.

Torque?? how i should know of this?? IM a beginner!!
According to Yamaha performance charts:
Alumacraft Voyageur 175 75HP 2075 lbs
4500RPM 27.7 MPH
Alumacraft 175 70HP 1994lbs
4500RPM 22.4 MPH
The 75 seems to do a better job no??
Torque = Couple moteur. 75cv plus couple d’70cv.

OK any drawback on this?? I mean, having more weight on the transom for a RIB boat.. Handling probleme at higher speed?? BOW always up in the air?? Stuff like that. 75HP is 100lbs heavier

I just want to make sure i make the right choice
If you have more weight forward, battery/fuel/helm etc. To balance the extra weight of the 75hp engine, I would go with the 75. The extra torque will compensate for the weight.
All IMO naturally
