Re: Johnson 88 SPl 1993 low RPM problem
Problem solved, the last matter to fix was water in the tanks. Now the boat jams. I was getting 35mph @ 5200 RPM with a SST 15x13 3/4. Now it seems maybe my tach is off by a few hundred RPM. Those #s show 6% slip which seems too good. I'm thinking it is more like 5500RPM. I am now getting lots of ventilation, I think I am going to lower the motor one hole. What do you guys think, thanks for all the help.
