Hi Colin . It's always an issue with older marine engines - especially inboards (outboards tend to have better parts support for some reason, and there always seems to be stocks of 2nd hand parts for older motors as the outboards tend to sell in thier 1000's... - though many of the items no longer produced rarely - if ever need changing - though it is alway that small - xyz part the gives the trouble. Certainly for many, the diesel engine is great as in parts of the country - petrol availability is poor, however Outboards have come on so far in the last 15 years - they have really closed the gap with fuel consumption etc. With your reasearch - you'll now know more about what it and isn't available than I. That said have many clients who have very obsolete engines - though still use them happily - though some DIY plumbing skills can be needed to make an after market manifold etc fit. Good luck with it. Best Regards Simon.

Hi Colin. I don't think an extra long shaft will be an issue in terms of being "Too deep" - infact the depper the better for an auxillery, but depending on your outboard bracket - you may find it difficult the tilt the engine up out of the water completely. I hd teh 6hp Yamaha F/S on the Navigator and had to fit "stand off blocks" to push the bracket further away from the transom when tilted up - the engine covers being quite bulky. I would have struggled with an extra long shaft - so migh be worth taking measurements before committing. Good luck with the survey - ensure care is taken with the sterndrive and the engine - some of the Volvo Specific parts on the engines are now difficult to get (she's a Perkins Prima from the Montego / Freelander under the VP paint and marinising kit). You'll also have the earlier generation SX drive I would suspect - if so - pay special attention to the power trim rams - they are terrors for leaking. Other survey items are standard - transom hammer testing, checking for cracks, damage, excessive moisture etc. Oh - also beware any leaks from the area of the hull / deck joint - abuse of the stanchions can cause the joint to open up. Best Regards Simon

Hi Colin. As you have the Family Pilot with the TAMD22/SX I think you should be going for an aux engine on the large side. I have found 4hp to be very marginal on a even with Pilot with a light engine and very little kit on board, but with the sterndrive you'll not be able to lift the drive clear from the water so i'll create a lot more drag, also your boat will be heavier. I'd certainly think along the lines of an 8hp or so as a mininum (Maybe a 6hp at the very very least - but I would go for larger). My first thought would be to go for an older 9.9hp / 10hp 2 stroke unit - lovely motors by Yamaha or Mercury/Mariner - ideally thier "Sailmate" type - these having the really long shafts and big props - they are not easy to find these days but worth it if you find a good one. Or go fourstroke - Yamaha have made a "High thrust" version of the 8hp and 9.9hp for years - these engines are lower geared and turn a larger diameter prop giving much better "push" for discplacement boats - certainly I think the better option. Mariner engines did the same type of unit called the "Big Foot". Hardy may have fitted outboard brackets as an option, but I don't think this was common, most were fitted by dealers and owners after built - thus many different types and sizes were used. Make sure that your spare engine bracket is rated to carry the aux engine weight (don't just look at 10hp ratings)- due to the heavy weight of the some of the fourstrokes - you'd need to be careful - i've seen a few showing signs of buckling in the past. There are some good heavy units out there to take 15hp / 20hp - these might be more up to the job if you're unsure. One last thing - look beyond the outboard bracket rating - check that the inside of the transom areas have been heavily reinfoced over the very wide area (i..e much wider than just the mounting bolts for the bracket) the big engines can cause flex - and you'd not want that!!! Best Regards Simon.

Gents, Have 75HP Honda. I have no problem with 5HP long shaft four stroke Honda, on Family Pilot. Great for trawling with enough power with four fishing on board on Firth of Clyde. Just set 5HP straight and turn main outboard for direction. Just like Mike said, not really used too much over the season. Still needs operate when required. Get this service annually along with main engine. If auxiliary is for piece of mind. In case of engine trouble, suggest you get something reliable and enough power to get to nearest port. Kenny

For what it's worth, my thoughts are - on my 17ft Navigator I have a 2.3hp 2 stroke. It gives me about 3 knots which will just get me out of trouble in the Solent but not much more. It's very light and robust and starts OK. If you do get a petrol engine, I would think you would need a 4hp two stroke jobbie that may give you about 4 or 5 knots. Most auxiliaries suffer from lack of use, so I don't know how robust an electric ob would be! As for stealth, I think a slow running small ob would not upset the fish too much! I would also always buy one of the well known brand names in any event. 2 strokes are lighter and easier to service than 4 strokes. Always buy new IF YOU CAN, or from a reputable main dealer!! If you buy privately check it out on the STOLEN BOATS web site!! Good luck!
