2000 chaparral 205 sse. 5.0 liter mcm gm v-8, alpha 1 gen 2 outdrive. engine serial number 0L640839, transom serial number 0L835800
Bought this boat in feb 2018. The previous owner winterized it (antifreeze thru muffs and into thermostat housing). So after visually inspecting things i decided all was well last weekend and took boat out for first time on sat. It did not want to start/stay running but eventually it stayed running. The boat ran poorly from engine point of view. Stalling/hard starts/bogging/under revving/over revving/backfires or missing etc. So i phoned previous owner and he informed me he did not treat fuel when boat was shut down in oct 2017. So i topped tank off the next day with 93 octane, a can of sea foam, and some 104 octane booster. The engine improved the second time out. Missfired/bacfired ocassionaly and ran great @ wot. After researching ive learned the thermostat was never in the boat when the previous owner owned it. Now im assuming that the choke is probably staying closed (due to water temp send unit never telling electric choke to open due to water temp never reaching proper range?) which is partially the problem as to poor engine performance. I also assume at this point plugs are probably fouled and carb may need disassembled and cleaned/rebuilt. On a side note i have fair mechanical ability and this is MY FIRST BOAT. Thanks everybody.
