    Spark plugs L77JC4 or QL77JC4, which is better?

    What is better to get if I run my outboards for trolling speeds? I have a 1983 7.5HP and a 1977 6 HP now in a good running condition but I want to get new spark plugs. They have currently L4's. Can't wait for spring to get it running on water.:D

    Johnson 7,5 HP seems to overheat

    I replaced the water pump impeller + all the tstat kit in this 7.5 HP. Before it didn't have a tstat in the motor. While running it (in a big 50 gallons barrel), it had good amounts of water coming out from tell tale but nothing from top exhaust ports and it should be I think. And when touching...

    Primer to use to re-paint a outboard?

    I want to re-paint the mid leg and lower unit on a Johnson 1983 7.5HP outboard. There are some areas specially on the skeg where it's bare aluminum. Do I need a special primer or regular metal primer is ok? This outboard will never be use in salt water. Thanks for helping me!

    6704M Evinrude 6 HP 1977 Problem: Does not idle long Work done: carb cleaned with new kit, adjust the low speed needle valve many times. I've opened up the magneto to clean it. Didn't change anything. Very good spark on both cylinder. Now this morning I found out that there's been a...

    Is it possible to rebuild a NLA Prestolite starter?

    The Prestolite starter (OMC 0380239) of my 1966 Evinrude Lark VIII started to turn weak at the end of the season on cold starts. Also there is a lot of a black powder on the starter. Brushes carbon I assume? Battery is a 2010, deep cycle always fully charged before getting the boat on the...

    What to buy for repairs manual

    I am pretty good to fix out outboards without a manual but I would prefer to have infos for some specified torques for bolts when working on the powerhead. I now have the tools. What can I buy? Evinrude/Johnson only. Thanks

    Problems at higher rpm's running in barrel?

    I am currently fixing 2 out of 3 outboards that I have purchased for not much, they have good compression, good spark. The 6 HP just have a new carb kit including a new float, and a new water pump impeller. Runs better now at lower rpm than before. But since all the lake are frozen, I can't go...

    Seals for a electric shift gearcase

    I want to save my Evinrude Lark VIII 1966! It ran very good all season but when it was time to winterize it, I drained the gearcase oil and it was milky (white but pretty thick). It shifts really good, no slippage so I guess everything is still good in the unit. I want to change the seals and...

    compression numbers

    I have tested the compression on those 2 outboards: -1977 6 HP Evinrude: 85 PSI on both cylinders -1983 7.5 HP Johnson: 85-90 PSI on both cylinders Also the head is a different white than the rest of the powerhead, the motor doesn't overheat, I can keep my fingers much more than 3 seconds...

    Would a 7.5HP be enough for a 10-11' ?

    I have 2 7,5 HP Johnson + 1 6HP Evinrude that I work on to fix them (minors repairs) and if I can't get a good price for them to help me buy a 15 HP, I would keep one 7.5HP. Would a 7.5 HP be strong enough to get a 10-11' out of water with 1 person or 2 max? Still haven't buy my inflatable...

    Purchased a 1977 Evinrude 6 HP for a hundred buck, the motor didnt run for a while but have several things to ajust and since I want to learn more in outboard mechanics this is the best way buying cheap. Of course it has sparks on both cylinders recent Powerpack too. It has 85 PSI on both...

    Setting up time

    I still wan't to purchase a 10 or 11' inflatable either in PVC or Hypalon. I would have to inflate/deflate everytime I would use it, I don't have enough room in my garage or even in font of my house to have it on a trailer. I know they come with a manual pump but I would maybe buy a 12V...

    difference between 1980's Evinrude/Johnson 4.5, 6, 7.5, 8 HP

    I have a 1981 Evinrude 4.5HP lower unit in good condition since the powerhead has no more good compression. In fact I wanted to re-build it but both pistons were different and rings for the 2nd are NLA. I've heard that they are the same as the 7.5HP models is this true or not? Is 6 and 8HP the...

    Can you believe that 2 different pistons in block

    Ok well I finally received my parts yesterday (piston rings and powerhead gaskets) to play in my first 4.5HP Evinrude that had compression problems. (I have a 4.5 Johnson also in good conditions) Well when it's time to put in the news rings in, one set doesn't fit at all. The grooves are not...

    electric shift lower unit seals replacement

    I had milky oil in the lower unit of my Lark 8. I changed the oil last time in July with new washers screw seals but no change. For now, I just refilled it up with BRP Premium Blend oil. I would really like to fix this problem but I wonder if it's a hard job and if its worth even if the kit is...

    white lower unit oil?

    I've changed the lower unit oil on my Evinrude Lark 8 40 HP (Electric Shift)and it was pretty white but not liquid. Is this what they call milky oil? If yes, for this very good running 45 yrs old outboard, how can I change the seals? Sierra still manufacture them but I'd preffer if possible...

    ZOOM 310 S by Zodiac Good or not?

    I wan't a second boat that I could bring on fishing trips or rivers and lakes closer from my house. I don't have a 4X4 vehicule and also, I don't have much place for parking in the city so a inflatable is almost the only possibility for a second boat. And they seem very stable and fast. Before...
