When I first started it a few weeks ago, I forgot to add oil to the gas. I'm pretty sure that is what destroyed it. Took a lot of work to start. Unfortunately, I did manage to start it and ran it for one minute or so. When I finally realized what I did, I drained the carbs and pumped gas-oil...
I have an Evinrude 90hp 1990. I've been working on the boat on land for a few weeks. It has run pretty well for the most part. A pop and stutter now and then at low rpms (on land pretty much all I do) especially when not really warm.
I have started it and adjusted things many times over the...
Just a followup. The new throttle cable didn't seem any smoother/freer than the old one when both were side by side completely removed from the boat. The old shift cable was a bit stiff.
I adjusted the trunion and the throttle does return to the idle stop screw. There was so much force on the...
Thanks, that's the word I wanted. I was going to call it the "truncheon" but then I went with "toothed wheel". I adjusted it a whole lot last summer. Maybe just adjusting it again (I worked on the carbs in the meantime and had it removed) will do the trick. And maybe first opening the remote...
It's hard to photograph, but here is the eye over the pin showing the angle. This puts lateral force on the cable and I think makes it harder to move in and out.
I have a feeling that even if I replace the cables, my sticking throttle problem will remain.
I want to replace the cables because I am having trouble operating the throttle. For example. If I lift the neutral idle lever, the throttle lever moves and engine speed increases. When I lower it, the throttle does not go back to it's original position. In the past, as screw holding the idle...
I want to replace my control cables.
The printing on the control cable housing about one foot from the motor side connection says:
OMC 103 4 M 1411
The printing is damaged and hard to read. Especially the last two digits "11". One one jacket the second to last digit doesn't look like any digit...
One more follow up in case someone else has warped bowls:
I reinstalled the original plastic bowls while I was waiting for the new medium orifices for the aluminum bowls to arrive. I thought I have nothing to lose, so I screwed the four screws securing the plastics bowls very tight (with rubber...
Engine ran quite well at all speeds for the last few weeks of the season, but there was a bit of a fuel leak, building fuel slowly in the engine housing.
Getting it ready now to put in the water.
* Engine will not start. It did start when on blocks last winter. A good amount of white smoke...
Just saw your reply. Thanks. The kits were OEM. I tried both old and new needles when trouble shooting. Old needles looked to be in great shape (but there could be something I don't see).
I did not remove any lead plugs.
Before installing, I blew in the intake to make sure it was air tight. On...
Got some more experience with this 14 x 11 prop. It's moving the boat a hair faster now: 22-23 mph, as fast as it's ever gone. Max rpms are 5100 to 5250. Seems to depend on the weather or who knows what.
Motor is running a lot smoother.
I'm going to call this problem solved, at least for the...
I installed a new 100 dollar 14 x 11 prop. I get
* 14 x 11 prop, 5030 rpm, 21-22 mph at WOT
* 13.75 x 13 prop 4800 rpm, 22-23 mph at WOT
I accidentally had my gps on a very low sampling rate for the 14x11 prop. I'll have to test it again later. I'd trust all those numbers better after...
My kid really thought it was a wilder ride. It was pretty obvious to me too. I trimmed the prop down a lot, too, so it was easier to stop ventilating (or whatever makes the prop lose bite) The speed was 23, sometimes 24. Hard to say what the max speed is because the gps speed has some flukes...
The new prop ordered online arrived: A 100 dollar Al 13 3/4 x 13 prop. I get 4800 RPM and 23 MPH at WOT (hits 24 MPH very occasionally). Same both directions, so I think there is no wind. With the SS 17 inch prop I got 4300 RPM and 22 MPH.
I tried to find more info on exactly which RPM gives...
