    What effect does motor height have on attitude (bow lift, porpoising, etc)?

    Hi Jim Alabama, As you know there's an eternal Hanky Panky going on on the forums with the nonsense that AV plate must be set higher or lower under the middle hull. As you have answered positively that now your combo performs much better with raised motor than did before, can you please...

    1996 Tohatsu M40C carb replacement

    Bad news, when restoration work is completed, would recommend to check the carb/timing synch of that motor, been finding lately several 30-40 HP motors running with less timing advance that what the factory recommends.

    Prop damage - should I just file it and repaint?

    Touche, was a visual moment, the skeg is bent, will need to have it repaired to its original condition. This prop had deeper damage at front and blade sides than OP's ones. A DIY Dremelization work and extreme patience did the restoration work, no prop vibration nor lower seals damage...

    Just for the record, with motor raised high, would you say that the combo is an excellent water performer on all water cond say : flat calm, windy, wavy, rough and at tight close turns at speed ? If with prop aeration on other than on calm water cond it's only good for running at straight water...

    Tohatsu 2stroke 30hp overreving

    Mmmm, whild guessing prop testing it's no bueno, time consuming along dumping $$$ into the deep blue... To have in mind : Was the over revving issue achieved when the combo was riding on flat, slight choppy, windy or rough water condition ? Was the motor previously trimmed to 90º (fully...

    Prop pitch suggestion for 2019 Yamaha vmax 90 sho

    Why do you run the motor trimmed up, don't know if fully though ? Combo should run parallel to water level once on plane, usually having motor set at 0 (neutral) trim as in pic. Distribute deck load evenly and try (1) setting. Any motor trimmed up will achieve a bow up condition, will make...

    Engine height... Excessive spray from right and left of the engine.

    Have you checked the lower leg side water splash by looking out transom at wot ? If not, how have you determined so ? Check this out : If rear hull is clean while water flow exits flat out at speed, the only possible way to achieve side splashes is when water flow bangs/skims lightly above...

    2009 30hp Tohatsu 2 stroke occasional power loss

    Rob, to get the max out of that nice 30 will need to be perfectly transom height matched along well propped. With a 11 OEM prop motor will be able to gain as much as 1K wot revs with 2 up and slight less with 3 up, for that to happen motor needs to be trimmed fully vertical (90 deg) on transom...
