Andronikos,
Dan Miller here from Skier's Choice. Chris Walker let me know that you might have some questions on an XLV.
Don't want to turn this into a commercial, but I will help where I can.
You are correct that the new E-coating used by Indmar is the latest-greatest treatment in fighting engine corrosion. It is pretty high-tech in that it actually becomes a part of the metal, vs. just coating the metal.
I would echo the earlier posts, that you should order the Saltwater motor, and a galvanized trailer. Cleaning the salt off of, and out of your boat and trailer after every use will add years to your enjoyment.
Regarding the Indmar vs. Mercruiser discussion, it is true that Mercruiser has more general dealers in some countries. However, many of them are not very familiar with working on Inboard and V-Drvie boats. Indmar supplies the top 3 inboard boat builders in the industry, accounting for 65-70% of the total units sold each year. PCM supplies another 15-20%. That doesn't leave much for the other guys. In both cases, Inboards are their specialty, and they provide the best product/service, because it is all they do.
There are two types of salt-water packages out there: Full systems, and half systems.
Full systems don't run any salt water into the motor at all. This is more like a automobile cooling system. Nice, but they add quite a bit more cost.
Half systems (most common), will run coolant through the main part of the motor to avoid corrosion in the most critical parts. The half system would pick up outside water, to cool the exhaust manifolds and v-drive unit. If you run the half system it is advisable to also add the flush kit - a freshwater hose connection, that allows you to flush the saltwater out of the exhaust manifolds, and v-drive unit after each use.
If I can be of assistance, feel free to contact me at the factory. I don't get the time to get on Wakeworld as much as I would like.
