>> My 5424 is a Kubota, and the Yanmar on my previos boat was also using a Kubota block, I really thrust them, but believe me that has been impossible to find used engines like yours.. The only one that I saw was Rich's engine, which I really  regret not buying ....
>> So, I have to deal with whatever is the best option on the market...  Right know, all the options point to Yanmar, which is also a great engine... I will install the best option, by means of HP, hours and price, It could be Yanmar, Westerbeke or Universal, NO VOLVOS!!!  Parts are veeery, veeery expensive, and sometimes are really hard to get !!!!
>> When you told me last time we spoke that you cruise at 6.5, that's when I put my eyes on bigger engines....Do you know what was the size of the original prop that came with your boat? I assume that Macavity came with a regular fixed prop....

>> Max,
>>     All I know about boat engines is that you have to add diesel to the tank from time to time or they won't run. The factory put a Universal M-35 4 cylinder in mine (hull 365 - 1990) It is turning a 3 blade max-prop and runs fine with about 32 horsepower. I run at about 6.5 knots at 2200 rpm and burn about .5 gal/hour. I have been told it is a Kabota tractor engine and parts are available around the world. My mechanic says Yanmar has the better marketing but Universal the better engine. Joe Launie/Macavity
