    1963 Evinrude 75HP Low Speed Jet Carb Adjustment

    Thanks guys for your input! I was think about trying another tank. The one on board now is home made thing the PO installed 20 years ago. He ran it on Lake Erie and wanted lots of fuel capacity.

    1963 Evinrude 75HP Low Speed Jet Carb Adjustment

    Symptom: While at idle or low speed, the engine "surges" off and on, as if it is moving between 2 and 4 cylinders kicking in. A quick acceleration typically results in a stall. Once at high speed/WOT, runs like a champ. Decrease speed to idle from WOT and runs rough and needs a little choke...

    Another leaking transom thread

    1990 Four Winns Candia 180, Cobra 4.3 After 2 yrs out of the water, I decided this summer it was going back in. Early struggles included bad gas and a dirty carb along with bad shift cable and suspect bellows (exhaust was ripped). I had the tank pumped, the carb serviced, and the shift cable...

    How to check fuel tank vent/ anti syphon valve

    There is a lot of talk about fuel delivery issues. Two areas discussed are checking the fuel tank vent and anti syphon valve. Not to sound stupid, but what do these look like and where are they located (besides the obvious answer- on the fuel tank). I have a manual that goes into great detail...

    General speed of 25hp jet ski

    Looking to buy one or two used jet skis for the family. We have only a boat now. My question in general is how fast a 25hp jet ski goes- I dont see this being more than just casual use, but I dont want to waste money either.

    Starter issues on a 1990 OMC 4.3l

    Last summer my engine compartment on my 1990 Four Winns Candia filled up with water thanks to a boat cover issue and a broken bilge pump. I got problems one and two taken care of, but apparently when the engine comparment filled up with water the starter submerged. I did the first start of the...

    Effects of bad OMC Cobra Gear Oil Change

    Last season, I had the local mechanic at my Marina (middle of nowhere) change my gear oil on my 1990 OMC Cobra drive. Not soon after, I launched her for the season, and that very day, I began experience the problem of not being able to shift to neutral, only forward or reverse. After some...

    Engine Additives

    I am running my 1990 Four Winns- (4.3 liter OMC w/cobra drive) for the first time this year in the lake. I ran it about 1.5 months ago on muffs in my drive and it ran okay. I am going to top off the tank and thought about adding Seafoam just to clean out the carb, jets, etc. Considering its a...

    Last night I fired-up my 4.3l Candia (1990 Cobra) for the first time of the season. Started right-up. I had the outdrive in the tub- the water intakes were about 1 inch below the water line, but all covered. It did not appear to be pulling-up water, so I shut it down right away and switched...

    Trim up or down while docked

    Sorry I am posting so much today! Its that time of year I guess. Quick question. When docked at the slip for extended periods, is it best to have the outdrive trimmed up or down? I left it down in the winter to avoid undue stress- I am assuming the same would be true while docked, especially...
