the engine hood I have is extremely heavy and to keep it open I use a pole. Not really trustworthy, does anyone have a better and more reliable invention on this?
We are talking about the doghouse right. Mine has the hinge on the deck (floor) and it flips forward. You might consider doing a change of the hinge locations. When I do a service or tune up I unscrew the hinges and move the doghouse and that leaves lots of room to work. It's easy to line up when I put the doghouse back and go boating.
consider making a simple prop out of wood with a "fork" at the end to keep it from slipping off, or hold it in place with quick-release alum pins. my doghouse is held down by cam latches but just lifts off or slides forward when those are removed.
