We found thje 1GM10 was fine, and the T28 is an even more easily driven hull so I would havwe thought that would be ok too.

I would say that the 13.5 hp option of the beta is probably the ideal engine size on current thinking. Anything bigger and you aren't working the engine hard enough, and certainly on the space for the prop on the 500/501 hull there isn't room for a big enough prop to use a bigger engine properly.

Original thinking was about 2HP per tonne for an auxialiary, these days that is more likely to be 4HP per tonne, which at around 3tonne loaded makes 12Hp for a 500/501

Mind you, now I don't own a boat I have a holiday each year on a tall ship and she only has a ratio of about 1HP per tonne, though she does have a bow thruster too.
