    Tohatsu 9.8 HP Revival.-

    Sorry, not being used on 2 stroke motors doesn't mean that can't be used to measure/adjust vacuum readings on any 2-3-4 carbed motors. For that to happen must meet these requirements : Somewhere to connect it. The connection will either be a blanked off screw hole or a stub for pushing on a...

    Tohatsu 9.8 HP Revival.-

    The video clearly states being a 4 stroke motor, was referring to the vacuum balancer brand and the procedure used. Dislike going per the archaic wagon method of counting the number of in-out turns when balancing the Pilot's Screw specially if a tree shade mechanic that abound down here has...

    Will depend if the manifolds or carbs have the vacuum ports to screw the vacuum nipples on higher 3-4 carbed 2 stroke HP motors. Useless for single carbed 2.5-40 HP portable motors. This is the Vacuum Balancer was looking for : Happy Boating

    Derating a 5 hp ( ca, 1995 model) to 4 hp

    If both 4 and 5 HP motors shares similar CC powerheads, mechanically restrict the throttle for the carb/butterfly to open say 3/4 when at full grip, change cowl's number and that's about it.. Happy Boating

    Tohatsu 9.8 HP Revival.-

    Thanks Paul, missed that one, first time seeing a motor running as such, definitely the lower crankcase is smoking not heavily though along squirting water at the pan, with reason the issue is canceled when the cowl is removed. What's the use of the Red Silicone for, definitely not right to seal...

    Suzuki DT4 Cooling Problem

    Are these examples from motors used in saltwater ? Does the motor have a flushing port around the powerhead or under the pan, if so will need a flush adapter, connect a garden hose there and flush with a much higher water pressure as long as you want. Can also flush with compresed air all the...

    Intermittent "cough" during startup.

    Coughs same on next day outing, say first start of the day ? Probably the motor isn't being fully warmed up in such scenario, runs too cold ? Are the t-stats in top working order ? If wanting to set all 3 carb's pilot jets to work spot on, need to buy an electronic vacuum tester... Happy Boating

    Thermostat housing hole.

    If I need to soak the splitted carb body usually use acrylic/lacquer thinner after all rubber, plastic parts were removed.. The soaking time will depend on how much gunked the carbs are found. Then can apply any Carb Cleaner Spray at each possible hole and dry with compressed air after...
