Re: Optimal rpm

 

 

5000 to 5200 is optimal for your newer 75 HP.

 

There are no yearly designations and haven't been since 2012. Even before then the other outboard manufacturers eliminate calling engines by year. Everything is by model number now.

Re: Optimal rpm

Thanks for the info Bill. The model is E75DPGLAF. I’m picking up my boat with that new motor on it today.
The boat is a 2004 tracker Grizzly 1860 utility jon semi v Hull with an add on side console. The hull weight is 595 lbs. I use it for duck hunting as well as pleasure and fishing. At times I have a heavy load. Most of the time the load is light to medium. I would like to get the most speed I can when loaded light to medium.(heavy is 1500+ lbs) (medium 800+lbs)
What is your recommendation for prop set up? I assume I should prop it with high rpms on a lighter load. Thinking of starting with a13.5 x 17 factory aluminum.
What is your opinion on stainless vs aluminum for this set up?

You do not have a performance boat so the choice is yours. If you run in a muddy or sandy area, the stainless is better and will last longer.  If you run in a rocky area, the aluminum props are cheaper.

Would the maximum RPM for a 2018/19 G2 E-Tec 225 HP be in the same ball park?  Trying to see if have the correct prop.

 

Thanks

5400-6000 rpm is the operating range --   5600-5800 rpm is ideal for all around best performance and economy
