    Cylinder Compression Incongruences.-

    Plan to replace the old narrow lubrication hose for a new wider hose to better the fuel/oil flow passing in between 1 and 2. Both current hoses are bit dried and hardened... As the nipples are fully pressed in and don't want to screw them as will be a nightmare to have them removed will be...

    Tohatsu 6hp still not broke in having carb issues?

    Would recommend order a Hardline hour/tach meter code : HR-8061-2 check Amazon, cost a tad more than other brands but way to go guaranteed. To get the full picture, aside the 25 HP that powers that 14 footer Sib, plan using the 6 HP motor also. Will both 6 & 25 HP motors be used at Lake Powell...

    Tohatsu m25c3 2-stroke compression high on one cylinder

    Forgot to ask you on my last posts when the center console's throttle is set to max forward, while previously geared forward, check if the white roller stops at the cam's middle indent/groove, if so, that's the 25 HP carb setting with the time plate's mark stopping at 20 deg. Or at the upper...

    2007 9.9 Tohatsu/Mercury. No sparks.

    Need to clarify which motor are we talking about. There's a great CC/HP difference compaing a 9.8 against a 9.9, both are different horses. The mentioned electrical parameters corresponds to a 2 stroke Tohatsu 9.9 model. Forgot to state the Ignition's Coil secundary reading which is : 4.1-6.1...

    Tohatsu 6hp still not broke in having carb issues?

    So, plan boating at 2 different altitudes, say sea level ? and a at Lake Powell right ? Nice to swap the carb for both altitude scenarios, but at the higher one will need to go for less prop pitch for the combo to run better than at a less height altitude. At your current boating location...

    Tohatsu m25c3 2-stroke compression high on one cylinder

    What you can do is : with left hand any finger rise the white roller fully up till stops, with right hand throttle the grip fully till the cam stops against the roller, slowly throttle the grip back and forth just a bit, if the synch is right should hear a light banging going on between the cam...

    Cylinder Compression Incongruences.-

    Been some cooling it's a very generous adjective, there was 0 cooling going on that exhaust chamber to the point that needed to take your palm out fast from the exhaust cover when monitoring the current working temp under load. There wasn't even a single water drop passing through under the...

    The Jurassic salted crust took 2 full hours to scrape and be fully removed, never have seen such scenario with the motors I'm currently selling and servicing. Salted water long time ago ate the whole anode located inside that cavity and replaced it by a salt clone, this complement shot of...

    2002 Tohatsu 25hp 2 stroke won’t start

    Now you've learned the hard way that when breaking in the new pistons and rings need to run the motor with 25:1 fuel/oil ratio for the next 10 hours, that means adding double 2 stroke oil dose to the normal 50:1 oil/fuel ratio. Check the Tohatsu's break in period chart in the Owner's Manual and...

    2006 Honda 9.9 Stalls in Gear in Idle

    When performing the idle screw adjustment and the slow rpm screw if having one must be done with the combo floating on water, adjusting it on muffs, barrel would be OK as a starter, but will probally need to be readjusted once on water specially the slow rpm screw if counting with one. Happy...

    If the fuel bulb was correctly primed with arrow facing upward till fully firm with choque pulled, that motor should start right up on first or second rope pull when performing the cold/morning start procedure given all the mechanical and electrical parts are in excellent working order which...

    Evinrude 28hp overheating

    Running in fresh water it's no indication whatsoever that the motor won't collect deposits, layers of whatever is found in fresh water, will do after 33 years of use, but to a less degree than when run on salt water for same amount of years. If a kettle collects deposits on lower base with...

    2006 Honda 9.9 Stalls in Gear in Idle

    To play with prop pitches the pro way need to count with a tach, with motor 100% healthy go for a wot run as loaded on flat calm open water and check the achieved wot rpm, from there can go straight for a prop maximization to less prop pitches once knowing that. It's extremely dangerous...
