    Tohatsu M40D2 Rough Idle/Not Reaching WOT

    Check when 2 up and at plane with OB trimmed to 90? if water flow passes under, way under small water deflector plate towards anticav plate height, forget by the moment all what's mentioned about anticav plate height. Having a jack plate to play with is a plus. This is the sweet OB/transom...

    This is the parameter I like matching when installingTohatsu and rebadged brands as well : Some concepts to get the idea clear : Taller water bed (1) produces better prop grip than at, (2) when OB sits at 90? best angle of attack is achieved while combo is at plane, if not, best prop thrust...

    Bingo.. Although trim was set to third hole out transom did not dialed what wanted, with the angle modification now dials spot on 90?. Combo floating by itself shows cow's logo being parallel to water level, this confirms how well OB sits angled on transom. On a 50 Km water test off coast...

    To check correct OB/transom height, throttle as usual and when boat is on plane trim OB at 90? to have hull and anticav plate riding paralell to water level, for that combo must be well deck balanced. Under those suggested conditions, try to adjust OB height on transom for water flow at speed...
