Engine installation, continued:

The work shown here took a long time - it was difficult to plan it all out in advance and I spent a long time deciding where things should go in an attempt to make maintenance as easy as possible, given the confined space in which everything had to fit.

With the engine in place I was able to couple up the Aquadrive and shaft to make a final check on alignment, complete the cutting out of the propellor aperture and fix on the skeg extension piece. This was a time-consuming job, partly because I was working in fairly primitive conditions and partly because I didn't apply any epoxy after midday - so it cured before the temperature dropped in the evening. Fortunately the daytime temperatures were high for the time of year, around 17 - 18 ^oC (epoxy struggles to cure below about 15 ^oC).

Skeg

The small space under the cockpit floor made it a bit tricky to squeeze everything in, particularly the Vetus water lock. This is fairly essential as it helps to prevent water flooding back up the exhaust pipe into the engine. It is not as low down as I'd like but this is the only place it will fit. I bonded three eye-bolts inside the hull and used some nylon cord to tie it in place. All the exhaust hose joints are double-clipped as the pipe is fairly stiff and heavy.

Key to these two photos:

1 - Cockpit drains (hoses not yet fitted)
2 - Exhaust hose
3 - Vetus water lock
4 - Halyard Aquadrive
5 - Stern gland stuffing box and cup greaser
6 - Cooling water inlet

All these components are expensive items. Water locks and exhaust hose can often be found at boat jumbles. For peace of mind I bought the seacocks new from ASAP (the only way you can guarantee the material they're made from).

Not visible in the above photos are the copper fuel feed and return lines, which run under the cockpit floor and are clipped to the plywood sides. The engine cooling water inlet pipe leads to a small remote filter, fixed to the side of the engine box - accessible from just inside the companionway. It has a clear top to make a visual inspection easy.
