    V6 running on 3

    Motor: 1990 Black Max 175. Thought my "off idle" miss was fuel related, but now find I am only running on cylinders 1,3,5. WhenI disconnected 2, and 4, and 6, there was no change in rpm.s. Obviously running poorly. Disconnect 1,3, and 5 separately and engine dies, or almost dies. In...

    I have a 1995 90hp Yamaha 2 stroke with digital Multi tach that is unreadable. I have an older style analog tach with lights. I would like to mate this up to the 90 hp. I have reviewed the past posts and looked over the manuals and electrical diagrams but can't figure how to hook up the oil...

    Yamaha 175 powerhead swap

    I've got a 1988 175 yamaha 25". I intend this winter to remove the powerhead and replace the steering arm. The shift shaft appears to have been replaced already as a magnet will not stick to it. I can see the holes where someone has drilled through the exhaust guide to separate the powerhead...

    Yamaha 1988 175hp. Thermostat cover bolt on port side, #4 bolt as marked on the cover. All others came out fine, but this snapped the head. The thermostat cover is off leaving a stud about 1/2 to 3/4 inch thick. I've read all the posts I can find but just checking on "best procedure" for...

    '88 175 Yamaha carb confusion

    Trying to lync and sync an '88 175 yamaha. The clymer manual gives different needle valve setting for different carbs; G501, G502, and G503 for the 175hp motors. My engine shows carbs stamped G505????? The Yamaha shop manual makes no mention of these different carbs. Any advise would help.

    '88 Yamaha 175hp; oil leakage

    Have done many searches and readings on this problem. I have an '88 175 with the old style pump; no check valves in line. When tilted forward, and to the port, I still get oil leaking out of the bottom carb (feeds 5 and 6) but it is on the high side (#5, not the lower that feeds #6) Having...

    Picked up the above motor and have been reading for almost a year, but I think previous owner got into the oil inject system. He has the blocking diode on the pink wire between the starboard temp sensor and the electronics box with the rectifier, brain box, and control box. My questions is...

    1988 Yamaha 175 and new tach:

    Picked up a new(er) tach for the '88 175. According to the Yamaha manual and the Clymer manual, the tach only shows a green and black wire for reading the rpm's. My new tach, analog, not digital, yamaha tach has 3 wires, G,B, and the yellow. I know yellow is keyed hot, but is it necessary for...

    Bilge Pump wiring/switch

    I am in the process of rewiring the boat. My plan for the bilge pumps, since they are so close to the battery switch, is to attach the positive lead, through a fuse, to the bilge pump, ~ 3 ft. then run the ground wire to the dash panel switch, and then to the ground buss at the console...
