I have a 1989 v4 90h.p with the port head running very cold. New water pump is pissing great and before I sell the boat and motor want it all perfect... I know Mercury's very well but don't own other Evenrudes so I believe that the port head could have a diverter or clogged issue.. I cannot...
I consider myself very good with Merc's in all aspects of doing water pumps, electrical, indexing flywheels etc....What is the secret when you can't even see the bolt that holds the shift shaft to the linkage on the large Johnson v6's... I have two of them that need pumps and I will be dammed if...
I surrender!!! I bought the motor and it didn't have a prop on it...never thought it was going to be such a pain to get a thrust washer...Closet dealer to me some 100 miles away is trying to sell me the seal/bushing that uses a spanner wrench to install.. I have that on the lower unit...Just...
We all know how bad the gas is today...Friend has a 15horse 2004 4 stroke carb model...his big 150 Black Max let him down due to an original fuel pump so he had to use the little guy to get back in.. He limped in on one cylinder...I was positive he hurt the motor but that was not going to be the...
I have a chance to pickup this motor and don't know anything about these..this engine has two plugs per cylinder. The question is about how reliable is this motor in regards to repairs etc.. I know they don't make these two strokes any more..Thank you
I wanted to catch all up on the latest which makes no sense...little background since it has been a couple of weeks.. I had no spark so rather then spend time testing, replaced switch box..Still no spark...disconnected yellow with black wire and also rev limited wire and have spark...put the rev...
I have a real challenge and need some outside advice...very knowledgeable with the electrical system on Merc's as I have many diferent h.p. motors but never a problem like this...When the blk/yel wire is hooked to the switch box no spark..disconnect it and spark on all cylinders...I checked the...
Very familiar with Merc's but looking for you guys to steer me on this one...buddy far away has no fire on the port bank of his v-4...What is it most likely... My guess is a coil..it has one power pack and two coils one for each bank...I am trying to get up to Reno to help test the components...
I was reading a post on here and wanted to share with all what it is and how to fix... I have a 150h.p Merc late model that I was going to sell. I dropped the lower unit, put a new pump in it, changed the oil and was ready to install. I could not get the lower unit to go into the power head...
I have rebuilt the carbs, retimed it, put new reeds in as old were leaking and it still had a terrible idle. Due to gasket leaking under power head, I have taken it to a guy who took it apart only to find the exhaust diffuser missing. The original owner says he took it out for better high end...
Hello! I have a 1994 200h.p. Merc that has a new power head installed. Afer starting it up I noticed water and exhaust coming out by the steering rod. Not a lot but should not be anything. Would your guesses be that the gasket was installed incorrectly or ripped when the new power head was...
