260 merc-syn. oil? ratio?

[1fastboat]

I might be buying a 98 20xdc Bullet with a 95 260 merc in a few days. What is the best oil?and what ratio is good? Can a higher ratio be used like 50:1 on days that I have a Bass tournament where less smoke would be needed and then go back to 40:1 or 32:1 on days where I dont have to idle and move my boat around 300 other boats at daybreak smokin em out!??

Pennzoil synthetic 32:1. Very little smoke on startup.

32 to 1, I like Mercury High Performance Oil. As long as you stay under 6000 RPM 50 to 1 should work. I could never trust my self to do that.

Under 6000? Who does that?

Mine only does under 6000 when I crank it over with the spark plugs out.

If you go'n let John port that 9.9 of yours, it'll turn over 6K too..........:eek: :eek: :eek: Don't forget, if ya put on does velocity stacks and does domed pistons ya'll was talk'n bout, ya better cut ya some louvers in that cowl and let er breathe some.

Well, I think the velocity stack (note: just one) will help a little bit. I'm hoping John's porting work will allow that 9.9 to turn up to 7000 or so. John, do you think we can adapt a Speedmaster to it?

Yea, we'll put a #4 speedmaster on it and run a duel stage NOS system then when you troll you wont loose that 5 MPH any more.

You guys said there was nothing to do to my 10 what is up with all these 9.9 mods???? Domed pistons...that's what I want and a louvered cowl. 15 hp I just know it. LF
