I’ve never had the pleasure of working on a PS34, but am intimately familiar with the engine hole on an
allied seawind II.
The SWII would be terrible with the original W-30, but a
repower to a smaller 3cyl engine makes it tolerable for smaller people. Our
boat came with a marinized Kubota 1105 (not a beta). This engine isn’t bad to
work on in the space. Normal
maintenance is no problem, more exotic stuff makes you curse, but it’s doable. A Beta 30 would make servicing items even easier as the engine is designed to be maintained from the front.
We did replace the standard packing with a mechanical seal, servicing that does require a fleet of midgets well versed in the arts of contortion.
