Hi Everyone,
Well I'm about to winterize my 2006 244 Funship Volvo Penta 5.7 GXI Dual Prop. Upon reading my manual, I discovered that there is a flushing adapter (looks similar to a dip stick tube) that you thread a garden hose onto. This is located on the starboard side of the engine. I'm assuming that this is used instead of a flushing muff commonly used on a stern drive. My questions are;
1) Have you ever used this flushing method on yours instead of muffs? If so, what do you think of this method?
2) The cooling system on this engine "is not" an enclosed type, meaning that it's a fresh water intake only system. Therefore antifreeze is not used. I have located all drain plugs on the engine in which the manual states to drain off along with removing the hoses off of the water pump.
My questions in this area are;
1)Upon draining the engine do you retighten the drain plugs and reinstall the hoses and add antifreeze to the engine? I may be wrong, but the way I understand it, is that all you need to do is drain the water from the engine.
2)The boat is kept in my un-heated pole building, therefore I'm thinking of leaving the drain plugs/hoses off through the winter. What would you suggest?
Everything else is pretty straight forward for winterizing.
Your input & suggestions would be most appreciated! Thanks

I can't help you with your flushing adapter question. Never had one on my engines, always used the muffs.

As for the block draining, I drain mine thru the petcocks and pull hoses the same as you. But I'm the worrying type. I always reinstall the plug and hoses then fill the block and manifolds with antifreeze. I feel better that way in case of trapped water plus the added corrosion protection that antifreeze gives you. Good luck!

Hi,
Sounds like a good idea, I'll do the same. Thanks!
