winterizing tige 2100i

[qwertykerr]

So i got a 1999 tige 2100i. MIE 350 MAG MPI SKI... First time winterizing. I put fuel stabilizer in. Changed oil and ran the engine for 5-10 minutes. Then i sucked up about 2 gallons of antifreeze... which turned out to not be enough.... But I am storing in my garage.

Question is... i pulled 6 water drain plugs, is that all of them?

Question #2 is ... and just pulling the drain plugs will that be enough or should I put them back in and fill the entire system with like 5 gallons of antifreeze until it starts coming out the exhaust?

Welcome. Where are you located? Is your garage heated or insulated? Do you know what your temp is in the garage? Do you have a heater or shower in the boat?

ps post some pics of your boat.

I don't think there is a heater... and there is no shower. Live in Michigan.

I see you changed the oil.. did you fog the heads?

DO NOT FOG EFI MOTORS!!!!!!!!!!!!!!! Use a 50:1 2cycle engine oil mixture from a separate tank and run it for 2-3 minutes. Also if you are not going to run antifreeze all the way through the block, be sure to pull the block drain plugs (9/16" hex heads) located center engine just above the oil pan on both sides, drain the exhaust manifolds and pull the lower hose off the circulating water pump.
