mariner 115hp 4sroke efi. to an brand new evinrude 115hp 2stroke e.tec d.i. 8200 british pounds i dont know what that is in dollars. my wife is giving me a hard time over this, but a man needs to fish
all the above . plus the need to pull off the head because the valves on the bottom cylinder needed reseating after 3years. i was told that they would need doing again in 3 to 4years as the salt water eats away at the seats. i take the head off myself so no labour charges but the gasket/parts prices are something to see and cry over. the oil cost will be the same ,i just w`ont have to jack up the boat on the beach to drain and refill the sump and then dispose of the old oil and filter. i think it was on this web site that someone said 4strokes are good but wait for the maintenance costs
