How do you expel the ingested water? Is it as simple as tuning her over with the plugs removed?

Got to love a 2 stroke - simple fix - no oil in the head to worry about ! I'm sure there was some liberal application of fresh water, then some oil in various places - plugs back in & purring away like a kitten...

Speaking to Matt he has been over the motor this week to ensure all is fine again

Same concept as RNLI OBs- drain all the water, turn it over , plugs in and off you go !

My answers are in your questions

Looking at my higher quality version before you tube recks it yes there was water coming from round the engine on that jump. From recollection this was my final pass over the waves and brief stop chatting to Avocet before we noticed Matt upside down.

2. How much did the lower sponson need to be deflated by?

Not a lot the weight of the boat upside down let the air out quickly

3. I noticed Matt climbed onto the hull near the stern, but later was pulling from much nearer the bow. Where was the best spot to right from?

The break in footage was no more than 6 seconds from getting on at the stern to walking further up the boat and getting the rope. That was the first attempt to turn it over

4. How did you drain the water out the powerhead and get it going again?
Matt and Whisper are best placed to answer this as they were there the rest of us bobbed about at Calshott waiting to get on it at Cowes

This is a fabulous video and we can all learn so much from it. Looked like a textbook recovery. Credit to all present for looking after each other and dealing with the capsize in a professional and seaman like fashion.

I wasn't there until after the wave jumping and capsize as AJ picked me up from Lyminton while the 4.7 was being towed back to Calshot.

We caught them up as they made good time in towing it back so I grabbed Matts car keys (luckily they were in AJ's pocket) and went on to Calshot.

By the time they had got back I had the car and trailer on the slip ready to recover

Pulled it straight out and to one of the hoses at Calshot where we washed down the engine, removed the plugs, filled the bores with oil and then blew out what was inside by turning it over, we repeated this several times, dried the plugs and then refitted them. Reconnected the fuel line and she started up.

Power tilt and trim was going up and down on it's own so we disconnected the trim motor and then disconnected the battery (which was dry) parked her up and then we were off to Cowes for the night

It was a large jump that wetted the power head ever tho i had prepped every connection and electronic component that needed protection. I assumed all to be pretty failure proof . All my yams have been in the situation before and never a misfire or hickup.
I ducked underneath and looking up through there was ample space to visually undo air cap. What was a bit unervy was as i was letting the air out the deck was lowering on to me so changed to the other side. Then shut the valves off for fear of water being sucked into tube which none did.

I let the toobs down 3/4 capacity to make the roll easier.

The rope i was hangin on to was the bow line fed throught the life line rope half way down the toob to give me angle of pull for a re roll.
I got on the hull from the stern as was easier as lower in the water.
Witha bit of help from the boys on the bouyant side lifting it went back over quite easily.

I used to race 2 stroke enduro motorcycles and regularly drown them in rivers in Wales - we would turn them upside down, kick them over a few times and then continue. When we got home we would change the gbox oil.

Cant say Id do that with a 4 stroke.

Sorry Biffer the problem is you tube and I used copyright music. You can view on a PC by clicking the link into you tube or viewing via the embedded link on rib net by clicking on the picture of the video.

Unfortunately due to the way adverts are displayed on mobile devices like iPads and smart phones they block viewing
