Can somebody give me a quick crash course in how boat speedometers work? I assume there are exceptions but just in general, how do they usually operate? Are they connected to motor or somehow just based on water rushing by boat?<br /><br />I've got an '87 Evinrude 90 V4 on an '87 Crestliner...
'87 Evinrude V4 90hp E90tlcur.<br /><br />Thought I'd pick up a set of new washers/o-rings for the drain and top plug of the lower unit. My top plug only has a nylon washer on it and the bottom plug with magnet only has a rubber o-ring. The parts schematic appears to only show one or the other...
1987 Evinrude V-4 90hp (E90TLCUR). Just replaced VRO pump and pre-mixed tank to make sure the new pump is working. Should I open the gap on my plugs to account for the extra oil that is going to get burned? Have about an 18 gallon internal tank on the boat and it's going to take a while...
1987 90hp V4, E90tlcur. Took it out of winter storage yesterday and ran it in a tank so I could diagnose fuel/oil starvation problem. Replaced bad VRO, buttoned everything up, and put boat in garage for the night. This morniing I've got four or five tablespoons of murky lower unit oil that has...
I have a 1987 Evinrude 90 horse V-4, E90TLCUR. Last time on the water, she'd get the boat up on plane but then cut out. Fuel bulb wasn't hard so I pumped it back up. Went for plane and again she would drop off, losing power but stay idling. Figured maybe I was running out of gas as my guage...
Thought I'd finally get around to doing the decarb on my '87 Evinrude 90hp V4, E90TLCUR. Read all the posts I can find on the process. Seems pretty straight forward but even though I've reviewed my OEM and Seloc manuals, I'm still not exactly sure where to connect the fuel line from my portable...
I've got a 2002 Mercury 90 horse, only been in service one year. Always starts find except the last two times we've been out. When cold, it cranks and cranks but just won't catch. Eventually it'll start and smokes a lot like it may be flooded. Starts fine the rest of the day. Haven't...
I've got an '87 Crestliner 17 foot fish/ski with an '87 Evinrude 90 horse V4 on it. Has been this set up since the prior owner purchased it new. Has had a stainless steel prop and hydrafoil on it for over 15 years without any problem. Not sure what prop brand or size is. Prop has some nicks...
On the last run back to the dock to load the boat yesterday, after a weekend of slow but pretty good bass fishing, my power trim/tilt wouldn't raise my motor back up. Motor is an '87 Evinrude 90 horse V4, E90TLCUR. Had to release the manual release screw and lift the motor by hand. The rocker...
Have an '87 Evinrude 90, V4, model E90tlcur. There appears to be what I believe to be a short (maybe 5 inches) ground wire that is between the motor and the tilt-trim. The wire looks almost braided, is very course (can't be bent without breaking) and has no plastic coating on most of it. One...
Stumbled upon an OMC OEM service manual that covers 88-115 and 150-175 Johnsons/Evinrudes. Copyright 1989. Covers the following specific 90 horse motors: E90MLES; E90TLES; E90TXES; J90MLES; J90TLES; J90TXES; and J90TLAS. As luck would have it, I've got an '87 Evinrude V4, model E90TLCUR...
I've got an '87 Evinrude V4 90 horse (E90TLCUR). I assume it has an alternator that provides current to the starting battery when its running just like in a car. I've got a manual but it's not helping me figure out how I can check how much juice is coming off the motor to the battery. I've...
I'm looking for a good evinrude motor mechanic in the Minneapolis / St. Paul area. If anyone can recommend someone, I'd appreciate it. Was hoping to find someone not at a dealer if possible. Have finally come to the realization that I don't have the time (or enough wherewithall) to do what...
My '87 Evinrude V4 90 horse has OMC controls hooked to it. Right above the ignition switch, there is a plastic "dial" that can be grabbed and turned with one's fore finger and thumb. Right above that "dial" are the cables coming out of the controls. I don't have a manual for the controls, and...
I've got an '87 Evinrude V4 90 horse. Just got it on a boat I bought. I ran the motor a couple of minutes with a motor flusher attached. About an hour later, when the motor was cool, I pulled the spark plugs to see how they looked and make sure they were set properly. One of the four spark...
