Hello Bob,

The BZ602 (Beta 16) is a very smooth running and quiet engine and is a much cleaner running engine than the old Yanmar. It meets all the new Tier 2 EPA requirements and this will mean less fuel used for a given HP developed. Future models will be upgraded to Tier 3 or 4. These engines are the latest Kubota blocks with the newest technology.

We can supply this engine with a new saildrive which will necessitate quite a bit of work but everything will be new. If your current saildrive is in good condition (the Yanmar SD20 saildrive has proven very reliable), we can also supply a new BZ602 (Beta 16) with an adaptor kit to fit onto your SD20 saildrive leg. If you chose this route, I suggest that you replace the diaphram gasket and rear mount. Another propeller with a bit more pitch or diameter to take advantage of the extra power is also a good idea.

Please contact me directly at the office and I will be happy to quote you.

Stanley
