    Best gas additive?

    Yes I have read some posts on this. But what is the best over product to add to the gas tank to clean and maintain a motor that is running fairly well? 1992-1994 Johnson 28SPL Outboard Thanks!

    What is my motor's true hp?

    I have a 1992 Johnson 28 SPL motor in nice condition. But I have read once or twice somewhere on the forums on upgrading that, because of a horsepower rating change back then, that my motor motor is about the equivalent of the previoulsy rated 35 hp and that the 20-35 hp versions were pretty...

    sail boat conversion

    Hi, I'm asking a question for my father-in-law who wants badly to sail but really does not have the cash to but any kind of sailboat. Only thing he has sailed is a snark and they are not the way to go on Lake Ontario and obviously have no room for more than one and you are basically laying in...

    Idiotic Transom Tragedy

    A few weeks ago, after installing a new jack plate, I did something that should disqualify me from ever using the term boat much less touching or driving one. I Basically backed the boat down the ramp and forgot to lift the outboard up. My helpers never noticed either. No matter now as we...

    Plastic prop stopping small outboard?

    We have a 2 hp Mariner outboard that runs like a top out of the water. But as soon as it goes in to the lake (Lake Ontario) it stalls out on a little 13" aluminum boat. Is it possible that the rather dull chewed up plastic 3 blade prop just can't cut through the rougher water there and a metal...

    Installing a simple small jack plate?

    I have a 15' fiberglass boat that is underpowered with only a 28 hp Johnson outboard. Top speed with a gps and one driver was 23 mph. But it would be nice to do that with 2-3 people if possible - or even 18-20 mph with 3 aboard. After researching here, I've discovered that 'part' of our problem...

    Hi, I have an old 15' Larson runabout with a 28hp Johnson longshaft outboard. See link below for photos. It is obiously badly underpowered but I don't have the cash for another motor. I'm trying to milk every mph I can out of it. Last year we maxed at about 18-20 (GPS) with just 2 people...

    Bubbles on hull after cleaning

    I think I may have a propblem - hopefully not to big. This week I cleaned my hull (70's Larson white fiberglass) with a prouduct I bought from the local marina. It said apply with a brush full strength and then was off with water. I did that and now there are hundreds of small bubbles all around...

    confused about hydrofoil performance

    I have been reading endlessly on this topic and can't seem to come to a conclusion. Bottom line is that I have an older 15' fiberglass runabount that is underpowered until a new motor is purchased. Has a Johnson 28 SPL Long shaft that peaks at about 10-11 mph with 2 people and maybe 18 with...
