    Stall at high rpm!

    You're welcome Ecoflorida, The only issue witht a motor runing on fresh or salt water is that the latter needs to be flushed way more to lessen salt formations inside the entire cooling water passages. If understood correctly, have split the hose line in two and both ends tank's and Racor's...

    Honda BF130 problems, needs input

    If need to retorque the motor gaskets after the break end period ends must be specified in the Service Manual. With respect to the torquing issues if Honda states to adjust bit passing their initial torque settings, no need to perform a retorque. Whereas when specifying just a timely torque...

    Honda BF130 problems, needs input

    4 Strokes motors tend to make oil, that's increase the level with water while mixing with the crankase oil, not salt water though. It's due to water condensation inside the crankcase. Probably there's an overheat issue going on on the crankcase and the heat sensor repetitively triggering into...

    Difference between 2014 Yamaha F8 and F9.9

    Before playing with prop pitches need to know the min-max wot rpm range factory stated for that 8 HP motor, install an induction tach, go for a wot run as usually loaded and report max wot rpm achieved. Test it with current prop, will know how much less pitch will need to go for the motor to rev...

    Thermostat housing hole.

    It's a bad idea to run any motor in a barrel as the motor will end heating up in a very short time. Can't cool a motor once the water has heated up. With muffs can gear the motor to run forward at a much higher rpm than doing so in a barrel. If you modify your current ear muffs can flush any...

    Star Board are running hot

    Well, until OP doesn't report if all went OK on a long wot run won't know if the motor is cooling properly or not ? One scenario is testing any motor on muffs, other much different testing a motor at load powering a boat at open water. If wanting to perform a water heat test in terra firme...

    Thermostat housing hole.

    Sorry for the brief interruption. Would advice to open each carb individually and check the internal cond, if the jets, main nozzle, needle, floats are in excellent shape no need to buy a full carb kit. If not mistaken Yams have removable needle seats, if those are what you're referring to can...

    Star Board are running hot

    Was that 34 year oldie motor run in salt or fresh water scenarios ? Run it hard at open water and check if the temp sensor if counting with one doesn't trigger and slows down the rpm. If all peachy, nothing to worry about. Happy Boating

    Thermostat housing hole.

    Touche, and lots of miss interpretation specially coming from you. Throttle down, hold your combo, no one said that all 3 PS comes factory adjusted at same height, a caliper will tell the height difference if such. OTOH why is everyone adjusting PS with exact number of in-out turns, if backed...

    Thermostat housing hole.

    If the middle and lower carb gaskets were dried, hardened and with fuel leaks, fuel spills should be found around the middle carb body and not exiting the carb's throats. Yam carbs uses large rubber o'rings gaskets not old school carton gaskets. If the motor now runs on premix 50:1 fuel/oil...

    Tohatsu 9.8 HP Revival.-

    My Boating Club wants to buy one so will take advantage of it. Useless for my boating purposes as I ran only single carbed motors which all of them retains their original carb factory settings to keep working delivered as Swiss clocks. No way Carbtune will search how many outboard motors comes...
