Hey guys, this must be my summer. JB et al the smart guys if you are out there pls give me an opinion.<br /><br />I ma the one with the Force 150 mounted on an 89 Arriva boat. R.eEcently I had the stator wires replaced and the thing ran fine(54 MPH - by the speedo anyway).<br /><br />Today, after spending the whole day detailing the boat out (and it do look good), we went over and filled the tank with 89 Octane (vice 93 that I have been running).<br /><br />We put it in the water and it started upand idled fine. Upon take off I noticed a bogging and bam it took off. It then started missing slightly at top end andthen seemedto clearout.<br /><br />Came back to dock. Went out again and it didthe same thing but not consistently. Sometimes it would take ff and move out fine - then it would bog, catch up and miss when we tried the sequence again.<br /><br />Could it be an air leak or fuel problem. The plugs look okay (lightly coated) soI am assuming it isnt electricla being it just got out of the shop few weeks back.<br /><br />Pls excuse the typos as this is my mom's system. The space bar works when it feels like it. <br /><br />Any opinions would be appreciated - especially since the boat is alread in the water.<br /><br />Deerdog

THE FIRST THING I WOULD DO IS CHECK AND SEE IF SHE IS FIREING ON ALL FOUR CYLINDERS ;BECAUSE YOU SAID YOU JUST REPLACED THE STATOR.AND TAKE IT FROM THERE?

Re: 150 force again

You should try typing with a squirely mini pin on yer lap that wants to play.<br />Well,she's too cute to just "sho-away", so i often put-up with her.<br />Anyhoo, yes, it could be a fuel/air leak. Check the bolts on the fuel pump and the carb,and the hoses. I've had the same thing heppen on a Force fuel pump. The screws backed-out in less than 1 hour op time after rebuilding it.<br />I decided to do what the manual sugjested, and use locktite on the threads, and re-torque. It cured the problem.<br />You could also have a coil breaking down,but they are pretty sturdy units.<br />Check the timing and timing linkage too, as that could cause the same symptoms.Again, highly unlikely,but possable.

12 Footer,<br />You are a genius. Thatis exactly what it was - the fuel pump bolt. It had backed out a turn. Anyway, tightened up with lock tite and problem gone.<br /><br />Thanks again<br /><br />Deerdog
