    YMIS Question! Ray Neudecker or Rodbolt around?

    I have a 1990 225ETLD. I just got the motor and I am trying to figure a few things out. I know these things have no timing linkage and the timing is controlled solely by the computer. I've read the service manual cover to cover, but it really doesn't cover this. While cruising anyhere between...

    '90 225 has a mind of its own.

    I have a 1990 225ETLD. I just got the motor and I am trying to figure a few things out. While cruising anyhere between 3500-4500 it will just all of the sudden speed up a few hundred rpm's like you hit the throttle. It will usually settle back down and may do it again. At higher speeds it...

    Will a 2007 Vmax cowl fit a 1990 V6 motor?

    Anybody know if the lower cowling and latches are the same on these motors? Have a damaged cowl and wondering what replacements will work.

    Yamaha 130 fouling cylinder #2

    I have a 1989 Yamaha 130. It runs perfectly but I keep fouling the #2 spark plug after about 15-20 hours. The plug becomes black and fouls out. So I am guessing that one cylinder is running rich. The pilot screws are all 7/8 out as per manual. The motor blubbers a little at trolling speeds...

    Volvo 3.0L loud exhaust?

    I am new to a 1995 Volvo 3.0L with a SX drive. First time out, I was surprised how annoyingly loud the exhaust was. I notice there are rectangular relief holes about 2" long above the cav plate. These are above the water while on plane and way too loud for my liking. Upon pulling the prop I...

    Creaky Volvo SX outdrive?

    I just picked up a 1995 Volvo SX drive with a 3.0L engine. After hearing a clunking/grinding in the gimbal area I pulled the drive. Gimbal bearing was shot and bellows ripped. I replaced the bellows and bearing and aligned the engine. Everything else looked good. The alignment however was...

    Volvo SX drive. Leaking. Why no gasket?

    I have a new to me 1995 Volvo SX drive on a 3.0L motor. I pulled the drive to check the gimbal which I could hear growling. It was worn out and a little rusty. There was a little water in the bottom of the bellows as well. The bellows themselves look in perfect shape. However, whoever had...

    Trim...Sloooow droop?

    I have a 1989 130 and the trim was dropping down slowly overnight. On a hunch I replaced all the o rings and seals on all the internal valves. Lots of fun! It seemed to be holding fine for a couple of months and now it has developed a slow droop. It will take about a week to drop right down. I...

    Horsepower of 1989 3.0 Mercruiser?

    Can anyone tell me the horsepower of a 1989 3.0L Mercruiser? I would be interested in the max RPM as well if anyone knows. It has a breaker point distributor and the engine number is 0B64577 if that helps. Thanks

    Anyone tried a 3 hole accelerator arm on Mercarb?

    I notice lots of posts on 3.0 Mercruisers bogging on acceleration. I don't see a lot of posts where they figured it out. Like many, my 1991 is doing the same. It is new to me and I have not yet water tested it as it was not even running well on the hose despite new points and plugs. I...

    3.0 Mercruiser Carb Troubles

    I have a 1991 3.0 Mercruiser. I just got the boat and have no history for it. It starts up right away when cold and as the automatic chock pulls back it starts to die. It seemed like it might be flooding so I pulled the carb and rebuilt it with the new style spring loaded needle and seat...
