Honda outboards offset crankshaft design - vertical shaft
Midpage of
http://www.temagamimarine.com/htm/hondaobm.html shows Honda's new offset crankshaft design. This might be useful for heli's where the crank shaft power output bearing must take high radial loads or the second shaft itself could be used as output. Crankshafts able to take radial output loads are not very common especially vertical shaft and 40 horsepower. Comments. |

Outboards generally are rather heavy for their HP, and their crankcases usually have a great deal of extra material built into them for mounting, clutch support, transmissions, ect. It might be hard to separate the "engine from the outboard." People in the past have also experienced problems with cooling, when converting outboards. The outboard always has a supply of cold water to run through it. Cold is a relative term, but consider that a closed cooling system may have the water enter the engine at 140 plus degrees. Water that warm is not sufficient to cool the outboard, in most cases. -- Jim in NC |
