'77 25' Catalina, 350 c.i., inboard. Practically no access to front of engine, other than a very, very small removable
4 or 5 inch access cover on a stair leading into cabin.
Totally inadequate!
Anyone or any thoughts on neatly cutting work windows in this solid fiberglass stair case, with some type of trim plates on stair risers going up cabin steps.
The engine's location has it's complete front, and belt driven accessories just buried under those stairs. Very poor engine location!
Any thoughts, or pictures will be apreciated.
