    smoke on the water

    I have a 4 year old Yamaha 15hp 2 stroke and it's smoking like crazy!...A LOT I took the carb apart and cleaned it, not much to report there. Changed the plugs with proper 1mm gap. The mix has always been 100:1 I took it out and ran it full throttle and it runs very well; smooth running and...

    tohatsu 9.8 corrosion on vertical shaft

    I have the Tohatsu 9.8 2 stroke outboard. The steering has become extremely stiff and there is corrosion/rust on the vertical shaft from the power head to the lower unit.

    9.8 2 stroke slowly fouling and stalling

    My Tohatsu 9.8B 2 stroke runs fine when first started. But after maybe 2 minutes slowly looses idle speed until stall. Plugs are very wet after stalling. I've shot carb cleaner thru and adjusted the mix screw with no success. Checked plug gap, OK. I dry out the plugs and let it sit for a few...

    which prop for my dinghy

    We're pushing a 10' RIB with a 9.8 Tohatsu 2 stroke. With one person, it gets on plane very nicely. But add a second person and conditions have to be ideal to plane off. The prop is stamped 8.5. Is there a better choice of prop to plane with a heavy load? Thank you

    oil leak from prop hub

    My Tohatsu 9.8 has been sitting since October when I winterized it. I was looking at it today and noticed an oil leak from the inside of the prop hub. There was no puddle on the ground, just a streak of fresh oil on the bottom inside of the hub. What's going on here? Thanks

    small twin OB's

    There are plenty of large twin outboard rigs around. How about rigging 2 6 hp OB's to a small boat? Two small engines are easier to lift on & off than one large one. There would be redundancy with 2 units and the ability to run on one when that's all that is needed. Rigging the two tillers...

    sportwin won't make full power

    I have a 1971 9.5 hp sportwin. It starts easily, idles smoothly and will rev way up in neutral but in gear it won't rev up nearly as high and consequently won't plane the dingy any more like it used to. What's up? Thanks
