Engine 2000 225 optimax. Model# 1225473wd Serial # OTO19488
New boat to me has 50 hours on motor but has been sitting for a long time. Compression checked at dealer was fine, they replaced high output fuel pump and all the hoses (Supposedly) Also replaced the ignition switch and checked all vent hoses in gas tank. New plugs but I had to re gap to correct (.032-.033) torqued down at 20#s. I have ran two tanks of gas through with mercury quickleen no ethanol in these two tanks. Runs great going down the lake to WOT but does seem a little slow out of the hole but again new boat to me. Starts right up with pumping the bulb hard prior to first start. Idles fair while in gear around 500 to 600 rpms. When in gear it has what I would best describe as a miss. It has never died and once over 1000 RPMS runs like a top. It runs the worse when I am done fishing have trolled into the dock turn it off then go get the truck. When I am putting the boat on the trailer is when I can really hear the (miss??) . After I re gapped the plugs it did run better and starts better but still has that miss at idle in gear. Voltage is 13.9 at idle but it does not have the correct battery in it so replacing that today.
