    Honda BFP60A will not exceed 3800 rpm

    If you decide to troubleshoot the tach, then if you don't have a shop tach available you can get a combo tach/hour-meter on Amazon for around $20 that just wraps a wire around a spark plug lead to get its reading. Many of them will remember your max RPM (read the features before buying), so you...

    2000 tahatsu 25hp 2 stroke worth

    I don't know if JB Weld type epoxy would do the job or not? Whatever you use, surface prep is going to be key to making it stick so be sure to follow the directions for whatever epoxy you get. I just googled "flywheel magnet epoxy" and got a bunch of info and videos, so give that a google and...

    2000 tahatsu 25hp 2 stroke worth

    Can the old magnets not be re-attached? Or were they damaged when they came loose.

    Honda BFP60A will not exceed 3800 rpm

    If you look at the spark plugs, does it appear that all cylinders are firing?

    Honda BFP60A will not exceed 3800 rpm

    There is a prop calculator on the Honda marine site, but it seems useless. Edit--> I read the wrong motor. If I'm reading this right, for your BFP60 for a 25+ foot pontoon they're recommending 14x11R so that sounds like you should be right.. hmm...

    Honda BFP60A will not exceed 3800 rpm

    Does the rental company have any other similar boats with the same motor for rent? If yes, go take one for a spin and see how it performs. If it's better, compare the prop on your boat to the prop on the rental. My point is, if the motor appears to run fine otherwise and there's nothing...

    8hp starts but runs only at high rpms

    I'll put $1 on low compression. A 2-stroke that acts lean, won't run at low RPM and lacks power is a common symptom of a damaged piston and/or rings. It can be a symptom of other things too, but you've already ruled out the carburetor and the fact that it was run wide open for a while just...

    90hp Nissian won't open up

    Wow, that sounds like it was all out of sorts. The info on the prop sounds odd to me, do you know any more about the back story on that boat/motor combo? Did the previous owner use that same motor on the same boat with an 18" prop successfully before you bought it? The difference between 18"...

    90hp Nissian won't open up

    If it worked fine when you put it away and now doesn't work fine, the most likely cause is plugged up carburetors. Especially if bumping the choke makes any sort of improvement. If you have compressed air, I would re-clean the carburetors and follow the carburetor cleaner up with compressed...

    Honda bf50 spark and carb issues

    The main difference between outboard boat motors and all the other motors is the raw water cooling system and associated corrosion and calcium build up issues. The rest is like any other motor. Corrosion is like cancer, an ounce of prevention is worth more than a pound of cure. Rinse like...

    Honda BF20 water in crankcase oil

    Yes I've heard about it before, we just don't see it much here so I'm wondering how prevalent it is. Do you see it often in your area? Our surf temperature here is already 80F and ambient temps in the 80's-90's so I'm guessing that has something to do with why we don't see it here much. I...

    Honda BF20 water in crankcase oil

    I'm conservative, not a big risk taker. ;)

    Honda bf50 spark and carb issues

    I think that was a typo and he was asking "did it come with" a flus port on the powerhead. Some motors have a flush port up by the powerhead, sometimes in the middle of a hose that you unscrew to attach the garden hose. These little Honda's have it down on the lower unit.

    Honda BF20 water in crankcase oil

    The making oil thing must be regional, here in FL I've never seen or heard of it happening to anyone I know, just rumors about it being a possibility for motors that idle all day. Maybe it happens in areas where the water is cool enough that the motor never gets warm enough to steam off the...

    Honda bf50 spark and carb issues

    If you want to remove all doubt as to whether it's your flushing adapter/muffs causing the problem, just put it in a garbage can or other big bin filled with water. You should be getting a strong stream, even at idle.

    Honda bf50 spark and carb issues

    Use the muffs instead of the flush adapter and see if that works better. The muffs, with a good hose, allow the pump to pump as much as it can, and I suspect that might be more than what the flush adapter gives you. Disclaimer; I've been using muffs on my 1999 since I bought it new and have...

    Honda BF20 water in crankcase oil

    It's impossible to say. How hard was it run with water in the oil and how long did it sit with water in the oil before the oil was changed?

    Tohatsu MFS50A intermittent power loss

    Does squeezing the ball continuously prevent the problem? I'm wondering if you have an air leak somewhere in the gas line between the tank and the fuel pump.

    Cutting out and stalling

    Just throwing ideas against the wall; when you replaced the water pump, did it get a whole new pump or just the impeller? Also did you double check the seal between the pump and the tube that takes water up to the motor? It sounds as if the motor might not be getting enough water flow at idle...

    Honda bf50 spark and carb issues

    Just to clarify my earlier post and add to what ahicks said; there will always be some water coming out with the exhaust at the center of the prop, more when the thermostat opens. I've never seen liquid water come out of the above-water exhaust on any Honda 50HP. I have seen a little bit of...
