    2022 Tohatsu 15hp Gear Oil Level

    First time knowing such oil check level procedure existed, wasn't mentioned before on previous Tohatsu motors. If you fill compltely the gearbox with an oil pump or squeezing an oil bottle till oil pours out the upper hole no need to perform that procedure, provided the gearbox doesn't have an...

    MODIFIED TRAILER

    Congrats, nice looking trailer. Plan towing the Sib with attached motor on transom or not ? So have added a transversal shaped rear frame seen on pic 5 to support the lower transom and motor, if so, nice. I usually end my back trailers to where both side cones begins, no need for the trailer to...

    Johnson Evinrude 15 vs Nissan Tohatsu 9.8

    For the ones that haven't tried running both CC motors powering medium light large applications 86 CC is a lot of power to count with and not need than.., you know the rest. Go for the larger HP motor, doesn't matter if weights more since you'll be sacrificing power against portability...

    Yam 85 Losing Power.-

    It's the same K prop type as the older one, with deck load evenly distributed the combo was running set at neutral trim. With +1 trim the combo achieved barely 0.6 Km/h more than previous max speed achieved. For me a spot on prop maximization will increase the extra top end speed achieved...

    Johnson Evinrude 15 vs Nissan Tohatsu 9.8

    A 1993 and up Johnson are 250 CC motors compared to just 169 CC of the Tohatsu. No, cant bump a Tohatsu 9.8 to a 15 HP one, are different animals. The good thing about having too much plastic is that can remove both lateral covers and retorque the cylinder head and exhaust cover without needing...

    Yam 85 Losing Power.-

    Yesterday went for a Rib wot ride with the new 15 pitch prop and 3 medium weight boaters. On a flat non windy rowing water course the motor barely achieved a poorly 44.8 Km/H at full hammer down. Although planed the 5.0 Mtr combo fast at 3/4 throttle the top speed was very disappointing to me...

    No pee Johnson outboard

    Sate the method used to have thoroughly cleaned all water passages ? Last chance : Unbolt the lower leg, remove thermo and bolt cap on, insert a hose with adequate diameter to fit tight on to the lower water pick-up tube. Open fully the water faucet and flush the motor for as long as you want...

    2022 Tohatsu 15hp Gear Oil Level

    An Oil Pump it's a zillion times much better and efficient than filling new gear oil with the oil bottle, go for one. Simply remove both lower leg's oil plugs, screw fully in the OL nozzle at lower leg and pump a lot of oil till exists the upper drain hole, once there screw tight the upper plug...

    Trailering a Saturn FB385

    To start with both front and rear transversal wooden stringers should not be mounted on top both front and rear horizontal ones, all 4 should sit eeven flat for the Sib's tubes to rest with a better trailer support. Can't tell by watching a pic, but as of right now seems the Sib will rest on top...

    Trailering a Saturn FB385

    Some issues : How far do you plan towing that 385 Mtr Sib, with or without attached motor and what HP ? Will be launching it from a ramp, marina, beach ? If you sit right now the Sib on top trailer, the tubes will only rest at upper and lower horizontal stringers the rest will be suspended on...

    Trailering a Saturn FB385

    Both tubes should sit on top both bunks, not side them as will damage the floor's fabric under both. Turn both banks for that to happen. Towing with a deflated keel will go same route as the floor's fabric lying under the keel... Happy Boating

    1989 90HP Mariner

    Nope a cold motor will not trigger the buzzer, only when the motor has run for a while and the temp sensor has detected an overheat going on on the powerhead will trigger the buzzer alarm, no way with motor OFF. Out of curiosity, post Thermo, Popet Valve and both internal housings condition to...

    Flushing any salt water used motor for that long years for as long as you want is no indicative that will be removing salt build-ups on the entire water passages, and that's from long plain experience running and tearing salt water motors. When buying second hand motors it's a Must check the...

    Mariner Magnum 40HP - Starting Issue

    If the needle doesn't seal well against the lower seat will have fuel spills when the bulb is primed till firm. My carbs have been micro polished that way and can stand on my motor's primer bulb with no fuel leaks whatsoever. The good thing about micro polishing needle's seats is that will...

    Meanwhile can find a donor portable tank and hose to startup the motor read courtesy of FB the extensive Merc's Owner's Manual twice. The only written indication states to gear F or R from N at idle speed. In most motors while OFF you can attempt to fully engage F or R from R, sometimes will be...
