G´day fellow cat owners with outboards!
We have a 40´ Kelsall
with twin outboards on the inner side of each hull
. Access is via the cockpit lockers, ie. you lift
up the seat and there is the outboard
purring away. The outboards were originally Honds 9.9s but a previous owner in 2004 replaced them with Yamaha 8 HPs.
They cop a fairly rough life located so close to saltwater, never get a freshwater flush etc. Anyway one has now finally died and needs to be replaced.
With the remaining Yamaha 8 HP, it pushes us along at 4 knots in calm conditions and consumes 2 l/hr. The two engines used to do 6 knots together. If we are in a no wind situation, we only use one engine
, never both, and just meander along at 4 knots until the wind comes back. We only ever used both engines together for manoeuvering in close quarters. In fact, the dead engine has been out of action for the last 2000 miles, so we have learnt to get by with one, but we were pushing our luck a few times and we need to go back to twins.
For the next engine, I am thinking of the following alternatives.
1. Find another Yamaha 8 HP, so they are truly twins and can share spare parts
etc. It is an unusual engine and will not be possible to simply buy off the shelf, so this will take time.
2. Find a 2-stroke motor with more HP. This will be cheaper in the short term than buying
another 4-stroke. In terms of just doing miles in calm conditions, the currently working 4-stroke can do that. For high manoeuvarability situations, both engines (a 2-stroke and a 4-stroke) can also work together. If I need lots of power for a very short distance (eg. getting through a pass into a lagoon), the 2-stroke will be better than the 4-stroke.
3. Find any other 4-stroke, longshaft and use that. Higher upfront cost, better fuel
economy but what´s the point of that when we already have a 4-stroke in the other well?
So that is where we are. What do you reckon? Should I be thinking of something else? Any recommendations?
Anyone know of a long shaft outboard for sale
? Or Aruba
