sundancer 290 winterizing in the water???

[Y Knot]

how do i winterize the motors while keeping the boat in the water?????

You will need to bypass the water intake on the outdrives to accomplish this in order to run antifreeze through the engine raw water components. But considering this is also a good time to change the lower unit oil, why not do it out of the water and make it easier?

i can't, no trailer and it's stored in the water.

i figured it out though!

drained the motors through the 5 petcocks. after that i just took the hoses off in the front and poured in the antifreeze!

thanks though

Don't forget the rest of your witnerization tasks-freshwater system, generator, A/Cs, shower sump, etc. etc., etc,

You said 5 petcocks....per each engine right?
2 on side, 1 for manifold and one for block....which one is the 5th?

 

[Y Knot]

the 5 were per motor. 1 on each manifold, 1 in the front lower, 1 by the starter for the block and the other by the oil filter on the other side for the other side of the block.
