Re: Islander 32 Mkii
Hello Fellow Islander 32-mk2 Owners,
I own a late-1977, I-32-3, tall rig, deep draft, in San Diego. It's hull #103 (3303M77K).
The original tired old Westerbeke L25 was in it when purchased and within 6 months the
transmission totally failed. So, I decided to re-power with a new Yanmar 3YM20 (21hp).
I was actively involved in the entire process and installed new hardwood blocks to raise
the engine bed, for correct propeller shaft alignment. Since the re-power involved going
from 4-cylinders to 3, a new longer prop shaft was needed, and put in a new drip-less
coupling. I was able to use the old prop, because the old-vs-new engine had nearly the
same output hp. Love the Yanmar, but $12k for the entire re-power was a big decision.
I emailed the original designer Robert Perry (Seattle area) and for a bargain cost, he sent
me a set of the blueprints. I scanned (digitized) the hull longitudinal section drawing and
married it with the Yanmar CAD drawing. This allowed me to get very accurate new engine
bed + prop shaft coupling dimensions. When I bought my I-32, the original mfg. ID plate
above the engine had been removed / lost, so if a sailnet member could send me a high-res
digital photo of their I-32 plate, I could try to get a replacement made for my boat, at a trophy
shop maybe. Thanks,
