    Black Max 135 Running Well, but Difficult to Control Throttle

    Hi all. I have a 17' runabout with a home built aluminum hull extension. The engine is fairly new to new so I'm still working out some bugs. Currently, I can set the rpms to about 3200 rpm, but the engine creeps to about 4k, running well the whole time. I have traced this to a looseish...

    1992 135 Black Max Water Pressure

    Hey all. I have installed a new water pump, and poppet valve, thermostats etc., tenp guage. I have a water pressure guage installed. It used to max at about 8 psi, and now it will reach 25psi at high rpm. Its at about 15 psi at 3500 rpm. I'm thinking it's too high, given what I've read the max...

    1990 135 Mercury V6, What does this hose/connector go to??

    Hi all. I have a new to me 1990 135 V6. It has a hose with what looks like a coupling connector on it protruding from just above the lower unit. It looks like it should connect to the power head somehow. My father guessed it was a breather for the crankcase, so I extended it into the cowling...

    1990 135 Black Max Carb Identifiaction and Cooling water Flow questions

    Hi all. Trying to get a list of things to do together for the new to me 135. I'm trying to figure out what carbs I have, as they were supposed to have changed in 1990 1/2. What luck! The serial # is 0C283129, which has been inconclusive when I searched online. It confirms 1990, but not which...

    1990 135 Black Max, Ignition Issue?

    Hi there. I have a new-to-me 135 Installed on my 18' boat. I had it out for the first time yesterday, and overall I'm very happy with the install. I was running on the plane at 3200 rpm, and the rpm would intermittently jump to 4k or so. I suspect an intermittent spark on a cylinder or two. It...

    Temperature Guage, 1990 135 Black Max

    Hi all. I am the proud new owner of a used 135. I am in the process of integrating it to my old boat, then I can have some fun! The one thing I did not get with the engine is the temp guage. As gauges are specific to their resitance/temp curve, I need to get the right one. I've tried searching...

    How many have deleted the oil mix system on their Black Max?

    I just picked up a 1990 135 Black Max. Couldn't say no, it was too nice. It's completely stock, including the oil mix system. Now, whether to delete it and premix or not? I'm trying to get an idea of the percentage that have deleted them...and what style of delete is most done.

    1990 Mercury 135, Common problems besides oil mixer?

    Hi all. I'm heading to checkout a 135 tomorrow to replace my 1975 Chrysler 135. Any special things I should look for beyond compression readings, cooling flow etc? I'm familiar with two strokes, but not this particular engine. They have a good reputation it seems. Thanks, Chay

    Hey all. I had low compression in #3 cylinder. I pulled the head and found a broken head gasket, but I also found some broken rings on multiple cylinders, and some minor scoring. Can anyone tell me if you can get just the rings? Or would I have to get the Wiseco pistons loaded ($$$). Trying to...

    Canadians! Where do you get your Prestolite CDI parts from?

    Hey guys. I have a local guy I usually use for boat parts, however he may not know too much about this stuff. He's a rep for Western Marine (Vancouver) who is a distributor for CDI electronics, so it may work out. If it doesn't though, who do you guys buy from? I'm looking for a CDI 176-5095...

    Hi all. I've lost the bottom two cylinders on my engine. Well almost. Every once in a blue moon the 3rd plug fires, but poorly. The stator coil feeding the CDI box is toast...Infintie ohms and very sparatic voltage output, so the symptoms match the plugs. Just wondering if I should consider...
