    Hello, I am staring to sand down and remove the old cracked and faded paint on my cowling. Alot of the paint stripper say do not use on fiberglass or plactic. What is the cowling actually made of? I sanded down past the paint in one area, it doesn't look like fiberglass. So I got a paint &...

    CDI question

    This weekend I fogged my motor by removing all the spark plugs and spraying a liberal amount of Seafoam into each cylinder then replaced the plugs. I was told to crank the motor to work it in. Mindlessly I did with the key. The bad news is I didn't ground the plug wires. I only cranked for a few...

    On-board charger

    I got a battery charger you mount to the boat. Water and salt proof with 120 volts input and 14.1 output using 14 gauge wire. It has two outputs, one for each battery. The one set is for the starting battery, it has a 10amp in-line fuse on the positive lead. That makes sense. Now the second...

    Trim tab no help

    Hello, A while back I posted that I have a hard pull to the right. I was told to angle the trim tab/exhaust snout to the direction it's pulling. So I did that and it made no differance. Then I angled it the other way. That made it far worse, so bad I could barly hold onto it. Now the tab is...

    Intake

    I think I know the answer, but I have to ask. I recently added a cold air intake to my truck for more power. Added about 10 horses and sounds great. This got me thinking. I have a spare crowl for my 150. If I cut three holes right in front of my three carbs, remove the carb covers and...

    Attwood 6 gallon tank

    Hello, Last year I installed a 6 gallon gas tank made by Attwood I bought from Wal-mart. Hooked up a selector switch so I can feed off my main 17gallon tank or use my 6 gallon as a spare. It worked flawlessly last year. Had the boat a few times this year just running the main tank, no...

    Sputtering

    I've been searching on here for a while and can't find a answer. While cruising around at wot my motor runs great but while I pull it back to 1/2 throttle it sounds horrible for about a full minute then it mellows out. It sputters and revs. It will keep doing that for 1 minute. I considered...
