    1977 70hp Mercury stator readings

    I have been trying to test the stator on my 3-cyl. Mercury. I have found some of the info I need by searching, but I have an "extra" reading that no one seems to mention and may be the source of my problem. Here are my results on my four-wire stator: Red to Blue: 5.66k Red to ground: 156 ohm...

    70 hp 3-cyl. no top end power

    I’m trying to troubleshoot my ‘77 7-hp 3-cyl Merc. My gut feeling is that I’m just not firing on all cylinders. For background, this motor is new to me and runs fine on muffs. The biggest issue is a lack of power and stalling if I try to push it beyond 1800 rpm. I’ve gone through the fuel system...

    70 hp 3-cyl stator test

    I've searched previous posts but not quite found an answer. I have a '77 70 hp 3-cyl. that runs fine on muffs but stalls if I try to get it over 1800 rpm on the water. I've gone through the fuel system from tank to carbs - no change. It's as if I'm running on one cylinder.<br />I've got a Seloc...

    1977 70hp idle speed adjustment

    To get right to the heart of it, is there an idle speed stop screw on my motor? The only way I've found to adjust idle speed is by the length of the throttle cable. The stop screw on the side linkage doesn't come anywhere close to touching when screwed completely in.<br />Unfortunately, I've...

    how to measure Mercury control cables

    This may seem a bit dumb, but it's a relevant question. I've replaced an old Evinrude with a 70hp Mercury and need to buy control cables. I have some cables that don't fit, and I'm using those to determine the correct length for new ones. I don't know if I should measure cables from tip to tip...

    1955 Trailorboat aluminum runabout

    I've had this boat for two years and wonder if anyone out there can give me some background on it. I've contacted Klamath, who bought out Trailorboat, and while they were very gracious, they had little to offer as far as history.

    I'm looking for a motor to replace my worn out Evinrude. I found a 1977 70hp Mercury for $800. The seller is under pressure to clear the garage of his projects. It is complete with control box, cables, wiring and prop. Compression is 115 in every hole. All maintenance is up to date including...

    1972 65 hp Evinrude poor performance update

    I've finally got back to looking at my recently acquired '72 Evinrude 65 hp (65ESL72S). The problem is poor idle and poor high speed performance. It seems to be losing a cylinder while running. I've tried some suggestions from my last post. The spark will jump a 7/16" gap easily on all cylinders...

    1972 65hp Evinrude poor performance

    I’m still working out the bugs on my recently acquired 1972 65 hp Evinrude. I’ve kitted the carbs, replaced fuel lines, adjusted timing to the best of my ability (I do have the factory manual). <br />I am having trouble getting a smooth consistent idle, and top end is rather sluggish for that...

    diode up in smoke

    I was putting the last touches on my new-to-me boat before taking it out (1972 65hp Evinrude). When I connected the battery I noticed the voltmeter came on, which should only occur when the key is on, and went back to zero when I did turn the key on. <br />I started looking for crossed wires...

    '72 65HP gearcase seals

    Hello all,<br />My 1972 65HP is getting water in the gearcase. I've looked through the postings and see I need to reseal the lower unit. I've been looking online to find the seal kits, but can't seem to find a match for this motor, which has hydro-electric shift. I'm not too anxious to go to a...

    Evinrude 65hp water leaks

    I recently bought a boat with a 1972 Evinrude 65hp 3-cylinder. Aftter kitting the carbs I put muffs on and started it up. I checked to see that there was adequate water and found water squirting out of the lower unit in several different directions from small holes (not the flush hole) all about...
