115 is a lot of power for a 5.5 . The fuel savings and increased range from a 4 stroke would be considerable if you planned on using it for cruising.

give us a buzz tomorrow if we can be of any help.

I'm going for two stroke because it's on the boat ! The previous owner has only put up 30 hours in the one year he had the boat. And as the boat will be used for fun and as a "Daddys Toy".... my kids words, I'm not too concerned about economy. I hope I dont regret saying that.

Scotty,

I'm sure that you won't (regret it). Since the engine is in good condition (as I understand it must be in excelent), you don't have to go for a 4 stroke. I have this very engine for the past 5 years, on a Bat 9 Falcon X boat. Bought it new and it's running like silk. Needless to say that I don't have to crank the engine twice to fire her up after winter storage. Fuel consumpion 1 litre/mile on MUCH heavier than usual boat.
To give you an idea, completely empty boat, without tanks, A frame and accesories is 475 kg. I calculate the weight of the whole combination about 950 to 1050 kg with 2 adults and 150 lit of fuel.
With 19'' prop the engine tops at 5000rpm (I told you that the Bat is heavy). I shall put a 17'' to climb at the 5250 which is optimum for this engine.

Regards,

Luke.

Dublin Bay and the Liffey are really fantastic now especially at night.

Our gang from the School have been running Advanced powerboat courses there over the last few months .

Much more glamourous at night than our usual haunt off of the West Coast !

I am still wrestling with my conscience over the engine choice for our new boats (Honda may be winning the coomon sense battle !)

Best wishes and well wear Luke !

Honda

Honda have a mixed bag on performance of custermer service.

The engines are ok, but customer service has been dreadfull for HQ (not the dealers) in a few (rare) cases I know of.

Honda HQ need to pull socks up or customers will walk!

As I said good product though

If you have one of these engines they can be modified to run on all four. Think the later went back to running on all four cyls. Watch the fuel figures they can be expensive to run and are a very heavy engine. Had one on a Viper 5.25 and it didn't suit the boat. Switched to a 75 hp merc which although slower was much better balanced and had better fuel economy. Hope this helps. Pete

Where can I get hold of this modification. I have one of those motors and I what it to run on all 4 from the begining

Martin Stitt, the Mercury dealer in Larne, Northern Ireland did it for me, how I have no idea since it came modified, but obviously there is a cut out switch in the ignition. How about having a chat with your nearest Mercury dealer. Check to see if the later models have the same system if not you could possibly find a later ignition system.
