He has tried every prop pitch and diameter and found the best one for his application. We both use our boat for crabbing and my boat has more power and gets better fuel mileage. His motor has had some major problems, (dumping fuel out of the breather) and I have heard of some other motors in the 90 to 115 range to have problems also. A buddy of mine had a 115 Yamaha 4 stroke with less than 200 hours that had 30 psi compression on each cylinder. Mechanic said he could not figure out the problem. He changed his oil every 6 months and never run the motor over 4500 rpm. He went bought a 2 stroke and hasn't had any trouble since. Warren

bumping this thread.
Just recently rode on a boat with new Merc Verado. That engine is the daddy!! Easily trumps my yammy f150. It is more quiet, seems to be more fuel efficient, and is quicker. I guess that supercharger works! I think they finally got the kinks out of it.

Yes you are right DI are the best. I went fishing with a buddy of mine recently that had an OPTI and he got 7 - 8 mpg.

I get 3 to 5 on my Yamaha 150, depending on the speed.
Running at different speeds, last two times I ran my boat around 95 to 100 miles, I burned 24 gallons of gas. I thought that was good. My old 200 Mercury on a 21 ft. Proline deep V boat got around 2 mpg fishing offshore.

running at an average of 5K rpms (41-43mph) with a full load...3 men, fuel 44gal, 162 qt ice chest and gear I get a SOLID 4 miles per gallon with my 4 stroke 150 Yamaha. BTW, my boat has a dry weight of 1,700#...I think that is great fuel economy based on my comments. NO way a DI will get better...PERIOD...

Jahosaphet....if your last post was a question to me.....No it is not based on word of mouth or a sales pitch...It (the fuel economy I listed) is based on MY acutal use....REAL TIME DATA.

I'd say 2 stroke Yammy for reliability and weight. But I run an old Evinrude now. They don't make them like this anymore
 I sure would love for a 70 horse Yammy 2 stroke to show up at my door. I'd have the Ugly Mudda runnin' again.
