Greetings all. First post from new I/O owner.

My former boats were straight-shaft inboards, so I have a few questions about outdrives and I/Os in general.

We recently bought a used SeaRay (23 ft) and intend to use it thru most of the winter. It's stored on a trailer in an unheated garage. Current plans are to heat it in the winter (more on that later). I'm curious if the outdrive requires a heat blanket or if it will drain sufficiently like an outboard does. I assume it needs to be returned to the vertical position to drain. It will not be exposed to the elements, but will be at ambient temperature during the cold days.

Regarding the heat source itself: Current plans are to have a temperature-controlled heater inside the engine compartment, and an electric blanket (on low) wrapped around the engine as a backup. I've used this before on my inboards with no problems, but they are more tightly cowled and have no vulnerable mechanicals outside the hull.

I live in Texas, where below-freezing temperatures are somewhat rare, and will be able to keep an eye on the boat/heat when temps are forecast to fall. This should mitigate any danger from power outages, as I can open the garage and do a quick drain should a power failure occur along with freezing temps.

I'm curious what methods others are using to keep boating during the winter. I would also like advice/opinions on the outdrive itself. I've got one of those rare combos, a 5.7 Merc w Alpha 1 drive. :rolleyes:

Thanks in advance for any advice/replies. Trying to make sure I'm not setting myself up for problems.

Yes at a minimum if there is any cold weather brewing i would just pull all your drain plugs, most likely wouldn't take more then a few minutes. Then at least there is airspace for expansion. Make sure you have a somewhat fresh fuel/water separator....water (again bad)

Lookup a low temperature alarm dialer... have it call your cell if temperature gets cold. (should be able to find one battery powered)

Also would look into a "weather station" temperature thing that you can closely monitor the high/low temperature in the garage to help find any potential lissues with your HVAC system.

As Bond-O mentioned...just drain the block/manifolds/risers if it looks like freezing weather. The sterndrive will self drain when brought to the vertical. Unless you have a water intrusion problem(in the lube)the temps and extent of the below freezing weather you'll see there won't be a problem.

As far as the combo...unless it's modified...the Alpha-one won't be a problem mated to the V-8. As with anything else, as long as it's maintained it'll be quite reliable.

One thing I'd do(assuming you don't know when it was replaced)is pull the drive and replace the impeller and/or housing and check the alignment. Two very critical/rather easy items in the care and feeding of the Alpha one I/O system.

Also...peruse the "Adults Only" section...It'll steer you in the right direction.

Welcome to i-boats...the finest forum for all things nautical!
