I have been covering my whole boat with an 11/22 HFT blue tarp over a DIY frame of PVC and scrap wood for years. The outdrive and prop were always exposed, not the hoses and cable, but no problems to date except for the frame collapsing once or twice. (Since I can crawl in over the winter, so can the occasional cat, but they evidently do not like moth balls.) I would like to just keep the shorter cover that I am using now, which of course still exposes the outboard but would allow easier access to "exercise" the steering over the winter. However being shorter it will expose the fuel line, fuel filter, cables as well as the aft hatches which now get rain but no snow. I could always build a small shelter over that area anyway. Dumb idea? Its a 1999 DC180 Sea Pro. Does anyone leave the outboard and the fuel line/cables exposed in the winter ?
