    Very weird Yamaha issue

    Good point! My brain always wants to know the "why" but there's a lot in life that just doesn't give us those answers. Does Yamaha have an open questionnaire or do you just have access to some kind of Yamaha technician system?

    Very weird Yamaha issue

    Funny thing, I mentioned doing something similar on a different circuit to my buddy but we never did it. I will definitely try that. Just to further understand the logic, why would the low voltage on the yellow wire only/mainly occur under acceleration? Is there a system built into the CDI that...

    Very weird Yamaha issue

    Gotcha. So in theory, I could tap into just the yellow, charge wire, to the CDI unit and see if I'm loosing voltage on acceleration? Maybe best to just run the entire test on the Stator with a DVA? Also, where did you get that diagram? Worlds better than anything I've been able to find. Yes...

    Also, wouldn't low voltage to the CDI cause running issues as well? Misfires etc. I'm not questioning what you're saying at all. Just trying to understand it.

    Come to think of it, the Speedometer sometimes flickers too.

    Very weird Yamaha issue

    Meaning the Stator is going bad? Or what else would cause low voltage to the CDI? I bought a DVA I can test the stator with. I know this isn't the best indication, but the gauge reads 14.8 volts while under acceleration. Also curious, why would low voltage to the CDI only cause the low oil...

    Very weird Yamaha issue

    I'm helping a buddy on his first boat. He purchased a super clean 1994 Champion 187 from a gentleman who swore it ran great. The engine is a 1994 Yamaha Pro V 150. It does run great, but we are getting a low oil warning light on the dash anytime we try to get on plane. This boat is equipped with...

    98 Mercury 150 XR6

    You think the new one testing below spec should be fine? Ever seen that before?

    98 Mercury 150 XR6

    I actually bought a new trigger. Ohm tested it. Whats funny is it ohms tests about about 950 on all of them. Which is below what the service manual says they should be. Weird deal. Maybe its the meter i'm using.

    98 Mercury 150 XR6

    I have a new to me 98' Mercury 150 XR6. I bought it knowing it had good compression (125-130), but was not running right. This came on a 98' Nitro Savage 884. When I went to check out the boat/motor I could tell right away that the carbs were flooding the engine. Took it out on the lake and it...

    Should I trade my new aluminum for older fiberglass??

    I have a 2005 Fisher Pro Hawk 180. Its an 18'3 hull with a 88" beam and a 90 horse mercury on it. Its got new carpet/wood, water pump, tune up, rebuilt carbs, gear oil all done in the past 3 months. I have an opportunity to sell it for $5750 and buy a 1994 Ranger 392v with a 200 horse XRI for...

    Boat HP rating certification

    I have a 2005 Fisher Pro Hawk 180 (essentially a bass tracker TV-18.) That does not have a hp rating placard on it. I have read online of a rating up to 125 horse, but I also found a guy with that same boat that has a placard rating of 150. Definitely don't want to short myself on hp potential...

    Am I trimming up too much?

    I have a 2005 Fisher Pro Hawk 180 (essentially a Tracker 175txw) with a 90 horse Merc on it. Under full power if I trim up just one or to "clicks" too much the boat tries to turn left on its own? Anyone experience that before? I just trim back down and it'll bite and correct itself, but i'm...

    2005 90 hp idle adjustment

    Just rebuilt the carbs on my 90 hp 2 stroke mercury. Wouldn't idle before and now it idles great but a little high. My question is about the sequence of adjustments as the factory service manual is a little vague. I have the carb adjustment needles all 1-1/2 turns out from slightly seated. This...

    2005 Mercury 90 hp weird oily leak gear case/Grunge In Fuel Filter

    I noticed a real thick oily type fluid coming out of the lower unit "weep" hole. Started to come out when i was running it on muffs. I'm having a problem with it not wanting to idle at all. Runs pretty good off idle, good power. Anyone know what it is? Gear oil? Anyone know why it's coming out...
