The oil pumping regardless of gasoline in the line is a problem I had with my engines when I got older and they sat a lot. Getting them started for the then current outing, took awhile for the gas to get to the cylinder (even with pumping the bulb up to firm) but the oil was pumping as long as...
I would change your input from "oil" lines to "petroleum" lines since I have evidence of fuel lines breaking down and filling up fuel filters with little black (rubber) specks.
I get decades mixed up since there have been so many in my life but I think it was in the 1968 (?) model year, OMC came out with a 55 HP Evinrude "Triump" 3 cylinder, loop charged engine, with a new streamlined lower unit.....got rid of the protruding LU gearbox. A year or so later...
Can you examine the end (side) of the propshaft and look for a threaded area. Surely if there is a nut involved, and surely there is, there would be a threaded prop shaft. Once you knew the existence of threads, then you could go about how to grasp the "nut"parts you see so that you can...
Well they had to have something to advertise prior to OMC's patent on Loop Charging, running out (opinion). There was definitely something to it as I had superb fuel efficiency with that engine vs a 1972 Johnson 125 (engine rated, cross flow) I bought new, besides super hole shots and great top...
I have been a Turning Point Hustler prop owner for decades. I like all the things they do to an aluminum prop......however having bought a couple of the dual type 4 blade props, I'm not sure I realized what the designers had in mind.....I would think that having 2 different functioning type...
I am of the opinion that tank/meter mfgrs. deliberately set the E on the gauge with some level of fuel in the tank for safety's sake. I think I verified this over the years but have no exact instance nor exact measurement. Besides an "almost" empty tank is unreliable, especially in a boat with...
Yes sir. I used to have a picture of Roy Rogers driving his 16' moulded plywood Yellow Jacket with the newly minted 60 HP I6. I understand that he was a stockholder in the Yellow Jacket boat works, and maybe/or in Mercury Marine.....had the boat full of Dale Evans (wife) and his kids.
I...
......and then they tossed another pair of cylinders on top of that and came out with the Tower of Power......had a 1988 115....one badass engine. It loved for you to push the throttle to the firewall.
SWAG.....running without cooling/lubricating water on the impeller blades jammed against the walls of the water pump, my guess is that you ran the engine long enough to melt the plastic (not brass) ring on the impeller to the crank shaft. A brass to steel interface would tolerate a lot of heat...
I had a 90 and 115 HP 2002 engines. I eliminated the oil pump gear on the 90 because I felt like doing it, obviously running pre-max gas afterwards. I didn't feel like it on the 115.
One thing I noticed and may have been the reasoning for the initial change is that I'm 84 and don't go boating...
I'd clean up the threads on all screws with a wire wheel. If you have a set of "Taps and Dies", clean out the holes in the block....carefully.
You are screwing into a small diameter cast aluminum threaded hole. Don't get overly enthusiastic. If I were doing that job, I'd put all the screws...
