    1988 Evinrude 90 runs lean intermittently

    I overhauled my 1988 Evinrude 90 (new rings, new tstats, new water pump, cleaned carbs). Linked and synched on the garden hose. Ran great. I had run it on the garden hose about 4 times for a total of about 1 hour. Took it out today for first water run and ran great for first 30 minutes at max...

    Overheating issue newly rebuilt 1988 Evinrude 90

    A year ago, the lower bearing disintegrated, knocking a hole in the block "half" that bolts to the part with the pistons. A welder fixed the hold and I just completed putting this engine back together. The engine was stripped to the block, which was honed. The machine shop reinstalled new water...

    Engine started on 2nd try...

    ... after I overhauled the powerhead. Maybe for a pro - no big deal and to be expected, but for a scientist, albeit former certified auto mechanic, this is a big deal.

    Difference between rectifier and regulator/rectifier

    I started a rebuild on my 1988 Evinrude 90 a year ago, got busy, and didn't finish the rebuild until last week. Somewhere along the way, I lost the regulator/rectifier. According to this page and to my local parts supply house, they show both a rectifier part no. 66 and a regulator/rectifier...

    Identifying piston bore on 90 Evinrude

    I am having the block on my 1988 Evinrude 90 cleaned and honed. The machine shop wants to know what the bore is of the current pistons and I can't find any markings on the pistons. Where would the markings on an OEM Evinrude piston be to indicate if it is .00 or .010 or .020 etc.? They are...

    1982/1996 Evinrude overheat alarm

    I have a 1982 Evinrude 90 with newer controls, post 1996 I think. I recently replaced the water pump because it would overheat and steam would come out of the telltale. Now, the alarm goes off while it is on the rabbit ears. I have not run it in the water. I can see no indication that it is...

    1988 ERude 90 Crankshaft / Rod question

    My 1988 Evinrude 90 had been performing flawlessly. Today, while at about 2000 rpsm, there was an occasional clunking sound and then the engine shut off. I could not turn the flywheel. At home, I took off the heads and the cylinders seem okay. I can turn the flywheel counterclockwise several...

    Replacing seal around release screw on 82 Evinrude 90

    My 1982 Evinrude 90 developed a tilt fluid leak when I had to use the manual release. There is a snap ring that I assume holds in the seal. Has anyone replaced this? How nasty of a job is it? Thanks in advance.

    I have never replaced a head gasket as normal maintenance, but some say you should. Is this necessary?

    Lubricating binnacle? Cables?

    I have a Yamaha 704 dual binnacle with twin SWS II 200s. The engines are 1997 and I suspect the binnacles are the same age. Although the shifting works without obvious binding, it is clearly not as smooth as a new boat, which is especially noticeable when I am docking. Is there standard...

    Replacing lower unit seals Yamaha 97 200 SWS II

    My rh starboard engine got water in the lower unit. My mechanic can't get to it for 3 weeks so I am considering a diy. I am mechanically inclined and have done considerable outboard work before, but no LU work. I will then pre-emptively replace the seals in the other engine as well. When I...

    Rodbolt or Ray - Broken ground wire bolt question.

    Rodbolt or Ray: I broke the bolt that is at the bottom of the engine frame and connects to one end of the ground wire. The other end of the ground wire connects to the other part of the frame that holds the zincs. The bolt is flush with the bottom. Can I just drill a new hole next to it and...

    97 200 SWS II fuel delivery issue

    I took my boat out on Thursday and on the return, the starboard engine died (naturally, right as I was approaching the dock :-(. Once on the lift, I managed to get it started but it ran like sheet. I had to chock the engine to get it started and then it would die in a few seconds. I suspected...

    Rodbolt, Ray - dropped lower unit - now gears won't engage

    I dropped the lower unit on one of my 1997 Yamaha Saltwater Series II 200s to clean out the speedo hole and when I re-installed it, the engine won't engage into gear.<br /><br />Rodbolt or Ray, is there something simple I forgot to do or that I didn't reinstall? :confused:

    Ray, Rodbolt - need tilt trim refill help

    I just replaced the tilt piston of one of my 1997 Yamaha 200 SWS II. I replaced the other about 4 months ago.<br /><br />After removing and replacing the piston, the motor has lost prime. Currently, all three (2 trim and 1 tilt) pistons are down. When I try to raise or lower the pistons, the...

    Yamaha fuel management speedo GPS

    I have the Yamaha fuel management system, which I believe is a 1997 system. That was when the boat was repowered.<br /><br />I believe the pitot tube has fallen off inside. I can easily blow air into the hose, but there is no reading on the speedo. How difficult is it to put this hose back...

    Tilt trim fluid pink, frothy

    I had the pistons and seals replaced on my 1997 Yamaha SWS II engines last year. The other day, one engine was struggling to raise or lower. The motor was running but no progress. The engine could be raised or lowered once the pressure relief valve was loosened.<br /><br />I raised the engine...

    Ringfree shock treatment

    I have twin 1997 Yamaha 200 SWS II carbed engines, with 200 hours each. Half of those hours were put on by me over the last 1.5 years. I have not decarbed the engines since I have owned them and I have to assume that the previous did not either. So, time to do it now.<br /><br />I am going to...

    Leak in hydraulic tubing

    While replacing the fuel hoses in my 1989 25' Grady White Sailfish, I inadvertently drilled into a hydraulic copper tube that runs along the starboard gunwale. I assume it is for either the hydraulic steering or trim tabs.<br /><br />Can I just cut the bad part of the tube out and patch it with...

    Yamaha multifunction gauge lights

    I need one or two replacement lights for my Yamaha multi-function gauges. These lights are in a rubber socket and have two leads. Any idea where I can find these or what the Yamaha part number is?<br /><br />Thanks
