Re: TENDER 11 Four-stroke-power-cycle Engine

I probably will have to settle for [buying a four-stroke-power-cycle engine with] significantly larger displacement [than the current two-stroke-power-cycle engine on the TENDER 11] given those two options [for maintaining the same rated power output over a wide range of engine speeds]. To anyone wi...

I may buy a 15-HP or 20-HP SUZUKI engine. I have no experience with modern four-stroke-power-cycle small outboard en...
