Yes--- it involves finding EVERY drain plug in the engine and exhaust system, running some preserver oil thru the engine JUST as it runs out of gas and mixing the right amount of gas preserver to last the winter. THEN there is the fresh water system which needs a non poisonous antifreeze and proper draining along with the black and grey water tanks being serviced. If it has a hot water system, it needs to be drained.

Then there is the trailer bearings which will be full of water if you are going to store on the hard they will be full of water from the retrieval (don't get be started on bearing buddies) No body knows how to use them properly.

Oh ya- you need to service the lower unit for leaks and new oil, and check the u-joint boot for water and bad U-joints and grease the intermediate bearing.

But don't forget the drain plug or all this work will be for nothing as you will find a boat full or rainwater and a bent trailer.

What engine should fit my 28´bayliner boat

Yes there is. Saw one at a boat show and I believe it was also Swedish. You may want to look for used replacements on the web. I do not know where you live, but there are boats on the Great lakes with low hours because of the short boating season. There are also victims of hurricanes with good engines down South.
