I don't know how you feel, but I have had it with the present state of technology supporting the design of small the internal combution gasoline engines. They are extremely unreliable, never start when you need them, they are now so heavy it is almost impossible to drag them to a shop. I decided to go electric, there have been significant improvements in the technology which have made it a viable alternate to the gasoline engine. I bought an Epropulsion engine from Emarine in Ft. Lauderdale. I have cruised with it quite successfully for a year. Recently I noticed a reduction in battery life which did not seem to be what I expected . Since it had a 2 yr warrantee I took it back to Emarine (as a passing notice the manufacture's rep for Epropulsion it the ex owner of Emarine and has an office on the premises). They found the charger and the Li batteries to be ok but there is a circuit board in the battery that assures the safe operation of the Li battery as suspect. They, in a timely manner, replaced the battery with a new battery. This unusual act of responiblity today salvaged my cruise!! Emarine and Epropulsion deserves recognition!!
