    Old Larson All-American, either a '61 or '62. Does it have a serial # or vin #?

    I have an old Larson All-American boat that I have up and running and want to get it insured but I have no positive year or ID #. Is there a plate somewhere on the hull or a # stamped in the fiberglass. Man, I cant wait til summer. I hope the twin 80hp Merc 800's that are on it will push it...

    '92 Johnson 30hp. Pull cord came out. Easy to fix?

    I was starting my Johnson 30 today and the pull cord came out. The rope did not break, the knot just came out on the end. Would it be easy to pull the recoil assy off and fix it or should I take it to a shop?

    Rotting Transom on a 16.5 Tri-Hull

    I was in the process of switching my engines on my '62 Larson Tri-Hull 16.5ft. The plywood in between the sheets of fiberglass is rotted out. What should I do? The boat is a two-piece so I might have to use a dremel and cut it in half again and replace the wood. Would it be safe to use a 30hp...

    Checking and changing the lower unit oil on a 62 Merc 800 80hp

    How would I go about checking the oil in the lower unit of my 80hp Merc? There is a drain plug on the side of the lower unit. What color is the oil supposed to be? If I were to replace it, what kind of oil and how much would be required? I have read mixed reviews on the 62 Merc 800 Stick shift...

    Working on a Mercury Merc800, Need Help!

    I recently bought a Fiberglass Tri-hull Larson boat with a trailer and a Merc 800 outboard motor for $350. The engine was recently rebuilt and near each spark plug there are compression numbers. They are 1 120, 2 120, 3 125, 4 120, 5 130, 6 130. Are these numbers typical or are they above...
