    Flywheel Removal Tool

    That is identical to mine. I'm guessing they all come from the same factory in china. It should work for yours as well. Measure the flywheel hole, if it is 1 1/2", that tool will work.

    Lower unit noise investigation

    The upper driveshaft bearing is just a ball bearing style, and it moves smooth and looks perfect. The pinion, fwd and reverse bearings were all tested in their cups smooshing them together by hand and they were all smooth. Essentially the noise has to be the gear mesh when unloaded. There is...

    1990 Mercury 40HP

    Why not buy a new key switch, since it will come with keys? Trying to get keys to that existing switch will likely be an exercise in futility.

    Flywheel Removal Tool

    I recently purchased a pretty generic puller/lifting tool for my mercury. The tool says it fits most mercury 45hp and up, but it fit my 2004, 40hp just fine. I have used it to pull the flywheel, and lift the entire complete outboard off the boat. That is what it is designed for. As long as...

    Lower unit noise investigation

    Looking for a bit of insight, input. 2004 2stroke Merc 40hp ELPTO I recently replaced the lower unit with a parts one, and it all seemed in excellent condition. Upon installing it onto the power head and running it, I can hear a noise coming from the lower unit in neutral. At first I thought...

    Replacing reverse gear only?

    Hi guys, 2004 2stroke Merc 40hp ELPTO I'll give the story before I get to my question. I drove this thing into a rock, hard, while on plane at about 1/2 to 3/4 throttle. I got towed back to shore because the prop would no longer turn (Even though the engine sounded fine.) The prop no longer...

    BF25 gasket kit for cleaning carbs?

    I have a 1998ish BF25 that is struggling to idle. High throttle is fine. It really seems like junk clogging up the idle circuit. No problem, lets remove and clean the carbs. With the design of this damn thing, you need to pull the entire intake/carb setup as an assembly, and then disassemble...

    15hp 4 stroke lower unit changing

    Just to clarify, that housing spacer is just that. A spacer. It would need to be removed to shorten the outboard. Inside that are 3 parts that require the shorter version. The driveshaft, water tube, and shift link. These would need to be replaced/modified to complete the job. There are no...

    Popping and shaking

    What you are seeing is referred to as a lean sneeze. It could be the carbs out of adjustment, partially blocked with dirt and varnish, or lack of fuel delivered to them.

    Honda BF25A leaking oil when hot.

    Update time. Powerhead came off without a hitch. Nothing looked amiss with the gasket (metal gasket btw), or the mating surfaces. While hanging I fished around the water passages and found no blockages. Air blows through the block freely as well. The oil pan had a very slight bow in it from...

    15hp 4 stroke lower unit changing

    Woa, I thought I for sure read that you said tohatsu somewhere, lol. My mind playing tricks on me I guess. The same advise applies. You can see the differences if you bring up a outboard parts website. I'd post a link, but I'm not sure on the rules of doing such a thing because iboats sells...

    15hp 4 stroke lower unit changing

    Do you know the year of it? Tohatsu had a couple different ways of doing the shift linkage. You can likely cut off 5" from the bottom rod and rethread remainder. However a used bottom end should have the shift rod with it though since it is pinned into the gearcase. The water tube can just...

    15hp 4 stroke lower unit changing

    The biggest issue is the driveshaft length. The water pump tube, and gearshift linkage can be shortened without too much effort, but you really need to buy the correct driveshaft. I have a friend who cut his driveshaft down to length and resplined it, but he also works at a machine shop. If...

    Honda BF25A leaking oil when hot.

    Well... you were right. I actually found em before I read your message. These 2 little devils were causing all my grief! Revisiting the manual, it does indeed say 10 bolts. I should have looked a little harder before getting mallet happy. The result is 2 bent bolts. I cannot believe I...

    Honda BF25A leaking oil when hot.

    Well, I have the gaskets on order so I started to take this thing apart. I got the extension case off to expose the oil pan. I removed the exhaust pipe and water tube and all 8 bolts holding on the pan. It was fairly corroded in place but some whacks with a rubber mallet and it popped...

    Honda BF25 identification

    Something else interesting. I called Honda Powersports to order parts for it, gave the 2 vins, and they told me the outboard was sold and registered for warrenty Jun. 2002. That still doesn't nail down the year of manufacture, but it was unlikely to be sitting unsold for 4 years. I'll go with...

    Honda BF25A leaking oil when hot.

    The replacement was a OEM Honda kit. The outboard was run for an extended time on muffs while troubleshooting the oil leak/overheating issue. I just read that these are not very good at running on muffs because of the 3rd water intake (that I just learned about) by the trim fin. I am willing...

    Honda BF25A leaking oil when hot.

    When running under load for awhile, then shutting down, and tilting the motor up, oil was seen leaking from the lower cowl weep holes. Looking inside the hood, there is no obvious source of the oil, so I'm thinking powerhead base gasket. See pictures. I didn't think the motor was getting hot...

    Right on, I really appreciate it. I am having some trouble with this motor leaking oil, I'll start another thread to ask about it.

    Honda BF25 identification

    Thanks. Can you tell me how you came up with 98? I'm actually not convinced. Heres a bit more info. On the lower tray there is a EPA sticker that shows it conforms to 2002 US EPA regulations. On the hood itself there is a factory looking sticker that shows 2006. I know the hood is easily...
