    Value of Yamaha 25 hp outboard?

    Around here it's hard to sell a boat/motor combo like that for what its really worth. My experience is that there are so many other similar ones for sale that buyers tend to go cheap and get the combos in worse condition or they try to get you to match yours with a junky ones price. People also...

    Value of Yamaha 25 hp outboard?

    I second that location is key. However, I will say that in my area Yamahas are the most desired of the carbed 2 and 3 cylinder 2 strokes. Any time there is a motor lot for sale, the yamahas always go first. Often ads read "all yamahas are sold". Around here people still love their 2 strokes and...

    Mercury 150 Black Max ~1992 year model

    Thanks for the advice. This motor has already had the oiler deleted which is how I prefer it as well.

    For the stator charging coils, the manual says to check "between yellow and white coil wires" looking for a reading of 750-1000 ohms. In my experience of testing charging coils though, you are mainly looking for one not being totally shorted out and both coils to have similar readings even if...

    Mercury 150 Black Max ~1992 year model

    Yeah, the water pressure gauge is high on my priority list. This outboard will be used primarily on Lake Guntersville in Alabama which is a great lake and fishery but that's in part due to the massive amounts of eel grass and other vegetation. If anywhere aside from the main channel you...

    Mercury 150 Black Max ~1992 year model

    I found a digital copy of the manual I ordered but it's revision 2 opposed to the original rev I ordered. Oh well, I prefer a hard copy myself but the digital one will come in handy. I plan to go through everything you mentioned. I noticed the manual was very adamant about keeping the forward...

    switch box help Merc 9.8HP

    Here is a link to the CDI Electronics page I was referring to. It has the resistance for the stator. I will check my manual out in the morning and tell you what it says. https://issuu.com/cdielectronics/docs/dva_charts_961-0003_feb.2013_issuu?mode=window&viewMode=doublePage

    Mercury 150 Black Max ~1992 year model

    Appreciate the reply. I'll check gear ratio manually like you said...should be easy if its 2:1 and only require two turns vs 10. Do I need to check the poppet valve? I dont have any experience with them. Do they simply open at higher rpms to make sure there is increased waterflow, in a way...

    switch box help Merc 9.8HP

    I have a factory service manual and unfortunately it says use the "Thunderbolt Ignition Analyzer and to follow the instructions in the tester's manual".... so It's not too helpful there. Try looking up the troubleshooting chart on CDI Electronics' website. They should have some basic resistance...

    Mercury 150 Black Max ~1992 year model

    My dad recently purchased a 1992 ProCraft 180V fiberglass fish and ski boat. It came with what I assume is the original matching outboard - a Mercury 150 Black Max. Serial number is 0D145256. Against my advice he bought it without doing a compression test nor an on the water test and they just...

    1982 Mercury 9.8 Coolant Passage Blockage

    Yeah, this one has definitely faced some neglect paired with some interesting home engineering. A lot of parts for these are no longer available so maybe on the bright side parting out what is good will help someone else out there fix their motor.

    1982 Mercury 9.8 Coolant Passage Blockage

    Alright, got good news....I replaced the water pump cover with a NOS OEM one which included a built in driveshaft seal. After replacing it and reinstalling the lower I ran the motor in a barrel and had pretty good water flow and engine temps. I did notice it takes a bit for water to flow upon...

    Which remote controls for 1988 Yamaha 30hp?

    Thanks guys. Sorry for the dumb question. I just always lived that tiller life!

    Which remote controls for 1988 Yamaha 30hp?

    Thank you! I need side mounted so 703 would be it then. Been looking those up on some of the auction sites and seen very few used units available that don't look like total junk and/or are an arm and leg. The rest seem to be Chinese knockoffs.

    Which remote controls for 1988 Yamaha 30hp?

    I also would like to add, I would like remotes with built in trim switch as I have an aftermarket tilt/trim unit for this outboard.

    Which remote controls for 1988 Yamaha 30hp?

    I have a 1988 Yamaha 30hp, 3 cylinder, Model # 30ELG. The motor is currently equipped with a tiller and instead of having the starter and kill switch on the motor, it came with a keyed ignition and kill switch mounted in a 4"x4" electrical junction box which has been mounted to my transom. The...

    1982 Mercury 9.8 Coolant Passage Blockage

    The 3/8" tubing was too large for the motor's copper water tube - but I was able to use a piece of what I think was 5/16" tubing I had laying around to go over it. Then the smaller tubing fit well into the 3/8 tubing and I clamped them together and used the barb adapter to hook it up to the...

    1982 Mercury 9.8 Coolant Passage Blockage

    I bought a garden hose to 3/8" barb adapter plus some tubing. Couldn't find a good pressure gauge though. Gonna pull the lower again tomorrow and see if I can adapt the flex hose to the water tube and run it like that. Hopefully that will tell me that from there up is either clear or not. Then I...
