    1974 evinrude 4406r 4hp runs hot

    I’ve been asked to help with a young man’s motor, 17 yr old, and I got it running pretty well but it starts running hot after about 10 20 minutes. The impeller is working fine, I did the drill attached to drive shaft test and produces a good solid stream of water. But if I let it sit and idle...

    Tell tale or bubbler what’s normal w/o a thermostat

    Thank you all! Follow up question but in the same vein The bubbler hole has lots of exhaust coming out. At idle water barely bubbles at the foot. If I cover the hole with my finger it comes out of the foot. I suppose it’s the path of least resistance and the water pressure makes the...

    Tell tale or bubbler what’s normal w/o a thermostat

    Yes I’ve got it on my bench. I just wanted to be sure things were in working order before I took that plate off. It’s not easy getting that lower bolt off/on. Thx!

    Tell tale or bubbler what’s normal w/o a thermostat

    I have a 1974 15 hp Johnson 15r74g that does not have a thermostat installed. Bought it without one. I put new water pump and rubber grommet at inlet where it meets the power head. Is this a normal amount of water w/o a thermostat installed? If it sits and runs for a while the water will...

    Exhaust housing bushing/seal

    I’m doing some work in this engine 15r74g and the exhaust seal/bushing is bustifucated. It’ll work but I’m here… may as well go back with new. However, it’s no longer available from anyone but eBay. It’s 50 bucks on eBay but is there a known alternative you guys might suggest?

    Recoil spring spun in housing

    Yeah the lug was in the locator hole and tightened firmly. I’m just unsure how it happened. General wear/tear I suppose. It’s in my bench vise and I’m not inclined to buy new.

    Recoil spring spun in housing

    When pulling rope it sounded odd then I heard the spring unwind in the housing. Removed the pull start and found the tab had slipped into the housing. How does one repair this?

    Timing off due to throttle arm and cam follower?

    I tried the knock off adjustable cam follower and it bolts up but the adjustment hits the carb before WOT. With the adjustment of the cam throttle arm I hope to be in good shape. Thanks for the hint.

    Timing off due to throttle arm and cam follower?

    It’s running now. Haste makes waste. When reassembling I put the old needle seat in the place if the jet. When I pulled it all apart it struck me that both were new and it occurred to me what I’d done. Put it all back together, correctly, and after another good cleaning, and viola.

    Timing off due to throttle arm and cam follower?

    Did a bit more digging. Seems there is another cam follower that can be adjusted. So, I'll pick up one of those and screw in the cam to match the throttle control arm at the proper time.

    Timing off due to throttle arm and cam follower?

    I screwed in the Screwed in the slow idle until it seated then backed out twice just a bit of fyi to accompany my previous reply.

    Timing off due to throttle arm and cam follower?

    Added some tape to the cam follower and it starts easier but still with drill. Pulling is darn near useless It refuses to idle and still only runs at idle on full throttle or with choke closed.
