Our Price: $ 44699.00??
Yes, it can be used to heat up the engine. But be carefull as your climbing under the trailer, climbing in the boat, and moving around in the boat. You don't want the fake-a-lake falling off the boat while it's running.
It's much easier & safer IMO to run a hose adapter on the intake hose like Jay said. No climbing under the trailer, no issues with it falling off. All the parts were from Home Depot. And it's probably a bit less expensive than the one listed.
