    Re: Outboard Motors - Honda Size?
    Thanks for the info Greg.

    I measured the engine well slot at the point where the prop actually lifts through; it is 8 1/2". The Honda 8hp prop is 9 1/4" whilst the Honda 5hp is 7 7/8". so the 8hp prop will not fit unless I make significant modifications such as widening the space between the port & starboard well walls ie repositioning them. Having just had a flat fuel tank floor installed in the port side well compartment I would have to modify that as well. Too much trouble and more expense.

    So it looks like it is the 5hp after all. There are a number of advantages with that. It is an easy fit. It is $1000 cheaper. It weighs 27 kg (which I can easily lift) against 42kg. It is within the dinghy's outboard range -I currently use a Mariner 2hp which is underpowered.

    I read in a 1994 Cruising Helmsman where Alan Lucas gave a rule of thumb measurement for diesel power requirements for displacement yachts - 4 to 5hp per ton. Assuming this applies to my situation and given that AWOL laden weighs in at under a ton then 5hp should be sufficient.

    I think at this point I should stop fighting the problem and buy the 5hp. Already, having checked 5 Honda dealers I have prices ranging from $1875 to $1725. I have yet to start negotiation and still have the Brisbane Boat Show to attend at the end of the month.

    Incidentally, Honda do not make or fit a high thrust prop. One dealer recommended I approach Solas Props. Their web site indicates that a small prop would have to be especially made and that it would be cost prohibitive.

    Before I fully commit myself I'll check the tilt length and transom height measurements. However, as I have a tilting engine mount I have more room to tilt without using the motor's tilt mechanism.

    Thanks very much for your advice Greg. You have made my journey so much easier.

    Best wishes
