WIDE OPEN AND BARELY MOVING

[GUILL]

I JUST RECENTLY PURCHASED AN OLD SKEETER DECK BOAT<br />IT IS A 16FT. TRI-HULL WITH A '72 MERCURY 50 HP OUTBOARD MOTOR. PUT IT IN THE SHOP AND HE CLEANED THE CARBS AND CHANGED OUT THE FUEL FILTER AND REPLACED A HOSE. BECAUSE IN THE BEGINING THE BOAT WOULD SHUT DOWN WHEN PUT INTO FORWARD. WELL, IT GOES INTO FORWARD NOW BUT, FEELS LIKE IT IS BARELY MOVING WHEN PUT WIDE OPEN. I HAVE THE LEAST BIT KNOWLEDGE WHEN IT COMES TO MOTORS. ALL I WANT TO DO IS GO OUT FISHING. CAN YOU HELP ME?

Check your puel pump diaphram. Squeeze the primer bulb a few times and see if it picks up.<br /><br />Make sure your throttle plates are opening to full horizontal at WOT (Wide Open Throttle)position of throttle lever and are synchronized.<br /><br />And please turn your caps lock off.

Is the engine running at peak revs with the boat not moving? Might be a spun prop hub if that's the case. If the engine isn't making the revs, give Bear's suggestions a try. Also, check to see that you have spark on all four cylinders...<br />- Scott

Re: WIDE OPEN AND BARELY MOVING

Hi,<br />Thanks for the advice. I just got back to work and received the messages so I have not tried your suggestions yet. I forgot to mention that the mechanic said that the 4th cylinder loses compression. Could this play a role in my speed capabilities? When I placed most of the weight at the front of the boat, although it takes awhile, it does eventually plane out. But it is still slow moving.

KJG - Well ---- yeah - -- - if you have a 4 cyl motor and one ain't puttin out - - it sorta follows that you will not have the power that your are supposed to. What were the compression readings?<br /><br />By the way welcome! Lotsa help available here.
