    installed sbt engine in 97 ts 640, went to canal to break in the new engine, went 20% thottle for 20 mins then let cool down for 1 hr.
    went 50% thottle for 30 mins then let cool down, then i went 80-90% thottle after approx 10 min i started to lose power i went down to idle and the engine stalled, i tried 4 times to restart and it would not turn over i swam it to shore and found that i had sucked up weeds some went thru the inlet grate. this morning i removed the inlet grate and removed weeds removed cooling lines and checked for debris. i reattached the cooling lines, charged the battery went to restart and the engine will not turn over. any help will be greatly appreciated.

    Do you mean it won't turn over, or won't fire and run? Does it make any attempt to turn over, like do you hear a click or anything when you hit the start button, or does it turn slowly or what?

    the engine fires but it did not run or idle, however i believe i fixed the problem by adjusting the carbs it seems to run fine now.
