    hi all,

    I have an Orkney Pilothouse 20 and it has a mount for an Aux engine but I don't currently have one...

    How do I know if I need a long shaft or short shaft? What kind of power required? Thinking 4HP?

    I've got a 4 for my 17ft, I imagine you might need a bit more. You don't say whether your auxiliary mount is one of the 'telescopic' type, if fixed you need to measure the distance from the top of the mount to the waterline.

    My boat is the same size as yours and I have a Mainer 4hp long shaft. I don't venture far, and I wouldn't expect it to do much more than a few slow miles home in favourable conditions. If you really want something that will get you home (in waves) the 8 or 10 would be required.

    As always, it depends where you fish, in what conditions you go out, how well you maintain your main engine, who you go out with (do you take the kids with you?), how adventurous of spirit you are etc. etc.

    It's not a mathematical calculation, it's more about your expectations of what you'll be able to do come the day when you pull the starting handle on the aux....

    Measure from top of mount (in running position) to bottom of boat (where motor is mounted).

    I only have a 5hp Silver Centuary, it pushes my 20ft boat along ok & its quite heavy! Think your boat looks a little heavier so you may want to consider something a little bigger!

    Id say 8 if your down sully for example and have to punch back up channel against the tide a 4 is going to get you no where.

    Hi
    I would not go bigger than 6 as the 8 is a twin cylinder and very heavy. The new suzuki's are very light and can be put down on either side and you will get boat show deals for the next week or so and hence could be worth speaking to your local dealer!

    Allways take your local tide run into consideration
    So your engine can push past the tide flow
    Ie Spring tides

    4HP was on the boat originally but the old owner took it with him.

    Enginenis only 2 years old with full service history (it's being done again next week..... I'm sure it will be painful!)

    Will keep my eye open for something a bit bigger but with the boat being a Pilothouse not sure I could steer too well from the stern but will investigate further!

    Thanks for the help :)

    If you need to use an aux you lock it ,using the tensioner ,in the straight ahead position. You then use your main engine to steer with. I did this with an Orkney Day Angler and a Honda 5hp aux and it worked ok.
