We had a cal 2-27, and removed the engine (Yanmar) once to replace the shaft coupler- it was not that difficult once we figured out an appropriate block and tackle arrangement. Just saw an atomic 4 on sale at the Ala Wai for $200.
Replace with another A4 or rebuild the A4, its hard to beat the value of that old engine.

cal 2-27 engine questions
I am laboring over engine problems in my 1978 Cal 2-27 and would like any thoughts or advice.
I have a dead Atomic 4 with serious compression issues (3 cylinders in the sub-40 range, one at zero), with salt water in the cylinders. The water may be the result of cranking the engine with the seacock open. I am unaware if the engine has ever been rebuilt.
My dilemma is choosing between repairing/rebuilding the existing A4, replacing it with some else (e.g., Gray Marine gas engine or diesel), or mounting an outboard. Issues I am mulling over:
The boat is Hawaii, making parts and shipping a significant issue. Access to the engine compartment is very tight, and there is talk of having to remove the interior cabinetry to get enough room to make repairs or replace.
I have absolutely not time or inclination to do the repair myself, even with the encouragement of very helpful A4 sites like Moyer Marine.
I hear diesel replacement is expensive, and any replacement, gas or diesel, other than an A4 will require tricky readjustment of mounting and propeller shaft.
Controlling the outboard speed and transmission will be tricky while managing the boat tiller.
