Post 6 on here: crazy youtube rib video

If it was me I'd tale plugs out spin it over to expel any water then put the plugs in and restart it.
It'll want a good wash down once back ashore too...

Others might correct me but I'd be happy to leave em in, I'd wash everything off in fresh water afterwards and give it a spray with WD40 or ACF50.

Wash with fresh water then remove the plugs. Then trunning it over but for the first time be very gentle pulling the starter cored. If you go too hard it can cause hydrolic squeeze as the water cant get out fast enough which can crack and bend things. Pull about 50-70 times, which isnt that hard as the pluggs are out. Put the pluggs in finger tight and crank 10 times. Pluggs out and crank again 20-30 time to get the last of the water out. You can blow on the pluggs to dry and dip in some petrol and then put them back in tights and put the caps back on. The prime the fuel bulb and choke out and if poss get someone to hold the throttle flat out and give it a go.
The more time you spend getting the water out the better chance of starting. This is what we do with the Lifeboat's 50hp Mariners.

Go and see the Thundercat people in Southampton - Fiona Pascoe is lovely and they can teach how to do all of that and how to drive it quickly - then go racing!
