This will probably sound strange, I definitely thought it was! I recently cleaned my carbs and when testing performance on the water, idle is great, idling in fwd/rev is great, and if it ever gets on plane it runs great, but the only way I can get it to plane is to trim the motor way up, give it full throttle, and when the bow raises up and the motor starts to bog, then I trim back down and the motor starts to pick up and take off, then running fine. Any comments or suggestions??<br />15'4" Astroglass bass boat, my tach doesnt work to give that info<br /><br />Stumped and confused!

How big is your boat? ie;length&weight?<br />Maybe your under powered?
