Winterising advice for Australia

Hi guys...While most of you are dusting off your babies ready for another season, our cold weather is fast approaching

Was chasing some advice, particularly from fellow Victorians regarding the need to winterise my '95 PS 190 LT1.

I live in a semi rural area on the outskirts of Melbourne (Yarra Valley), and whilst our winters are no where near what you experience in US/Canada, it's not uncommon to get overnight temps at around 0 to -2C, with the lowest on record being 1 night last winter at -3C (26F).

Is there any need to winterise my boat, or should I just be preparing for the next season with an engine and trans oil change, new impeller, new oil and fuel filters and a new set of plugs?

...Another newbie question. When I used to ski with a mate 25 years ago behind a 350 chev powered Gilflite, he'd dry run the motor for 10 - 20 seconds (revving intermittently) after trailering to expel as much water as possible from the motor. Is this necessary/harmful/advisable for my boat?

Don't want to do anything to harm this sexy beast!!

Thanks in advance.

Cameron

I would not do anything, we keep our boat at Eildon and it would get similar temps. I do not start the boat out of the water at all, even to get rid of the water.
Generally late July I do put it in the lake just to give it a run and get everything warm and working.
Starting it in the shed is not good for the impeller.
Just get it serviced in October ready for the season. We now have a new Mastercraft Dealer in Derrimut.

The only thing you should really do is drain the block when it sits for long periods of time (weeks) water is electrolytic and like to eat metal - especially aluminum when it's connected to iron. disconnect all the plugs - 2 in manifolds / one on each side of block let it drain - put some anti-seize grease on plugs and put them back... then open the impeller - pull impeller - let that drain out. put the impeller in baggy - order new impeller and gasket - and call it quits.. If you're real got a case of the MCOCD fill the block with RV anti-freeze with corrosion protection - not so much for the antifreeze but the corrosion protection..

At those temperatures I don't think you have to do anything, but it wouldn't hurt to run some antifreeze (for peace of mind). I would also check with my insurance company to see what they expect for winterization - assuming they cover for this type of damage.

Do not run the motor out of the water. You will burn the impeller up. I would drain the block and call it good. After the normal oil change and such.

This is what I'd do too. Block/manifolds drained, and rest easy. If your boat has a heater or shower or anything, be sure to blow those lines out also... but past that, you shouldn't have any issues in those temps.

Here is the winterization checklist and shopping list that I put together a few years ago. It is as much a annual maintenance/storage checklist as much as winterization. If it is not that cold, you could possibly skip the antifreeze steps... but that would be anti-MCOCD!

pull the four plugs and impeller. With your set up it's super easy.

Open up the drains plugs mentioned and remove the lower impeller hose when you take out for the last time and drive home with them open. Hit a few uphills and downhills...after that, there sould be no need to dry start.

Thanks for all the replies guys...really appreciate it.

The other option is, of course, that I harden up and keep skiing throughout winter - there's really no good excuse not too given our lakes don't freeze up!!
