    Pulling flywheel 1990 3hp

    There's a bit broken on my fly wheel? Does it matter? It's a little fun, doesn't seem to do anything. Also what size of bolts do I need to pull the flywheel? Thanks

    Missing parts 1991 3hp

    Hi, I have a 1991 3hp, there appears to be 2 fuel nipples. Part 30 and part 31. Which one is the fuel inlet? I have the fuel line hooked up to the smaller nipple, part 30. But when I do I lose fuel through the missing part 31. Why are there 2 nipples? Where should the fuel line go?

    1990 Evinrude 3HP, dies when throttle opened more than half

    Hi, I bought a 1990 3HP cdoe: e3bresr. It wasn't running but has 120psi on each cylinder. I cleaned the carb out and put it back together. I can now get it started and it idles nicely enough. New fuel is in there and a pair of new RL82C plugs gapped at 0.035. She starts up easy enough, and...

    4hp johnson slower than expected

    Hi, I have a 1972 4hp johnson with the weedless drive. I've put it on an 8foot inflatableand I'm only getting 5kts. The boat only weights 25kgs and I'm of average build. Is that to be expected? I think my main question is if I'm able to find a standard rather than weedless drive will it make...

    Johnson 4HP questions

    Hi all, Got myself a 4HP 2 stroke today, and an 8 foot fibreglass dinghy. I put the motor on and threw her in the water but she wouldn't start. However I didn't have any tools and it was getting dark so I'll start trouble shooting in a bin tomorrow. It hasn't run in 4 years but I'm told it...

    Short vs Long Shaft for 4hp

    Hi all, I am looking for a Johnson 4hp to put on a small inflatable 4 person dinghy. I expect I need the short shaft version of the motor. When looking at used motors online how do I tell if its short or long shaft if the seller doesnt specify? Do they have different model numbers? Thanks

    What to do with old 2 stroke mix

    I have about 25 litres of 2 stroke petrol/oil mix, that I mixed up about 2 years ago. What should I do with it? I have heard it can harm the engine, if it runs at all. Ideally I'd rather use it than throw it out, not least because the eco centre which might take it is a long way away. Could...

    Absent Drain Tube

    Hi, On my boat there are 2 drain holes. One in the splashwell, which is a 1 inch hole through the transom and seemed to be simply a silicon coating over the wooden transom. I pulled the silicon out and the wood is a little soft. One at the bottom of the transom where the drain plug screws...

    Loss of power, won't plane

    Hi, I have a J100TRLCSC and when I was out the other day everything was great, until it wasn't. I was pulling a tube and after swapping riders and restarting the engine I couldn't get up on plane. Boat seemed really down on power and was difficult to start. It wasn't a gradual thing, it was...

    Should I add a fuel filter?

    Hi, I have a J100TRLCSC. I was surprised there wasn't much in the way of filtering for the fuel. It seems the pump as a screen in it but that's the only filtration. Should I add an inline paper filter to the hose after the primer bulb? Or maybe a water separator? Thanks

    Switched 12v

    Hi, I'm new to boats. In cars there is the concept of a switched 12v line which is live when the ignition is on. Do boats with an outboard have a similar concept? If so does it work based on the key in the remote control unit? If not then are things like lights, horn, speedo, fuel gauge all...

    How do I fix this ladder?

    New to boats, just bought this one. Looks like the ladder is attached with self tappers which have pulled out. How would I fix this? I was think.of using Bondi glass to fill the hole then redrill it? Are self tappers string enough here? Also seems that the bracket isn't flush against the hull...
