Dilemma which engine to go for

[Scoobysnax]

I am purchasing a 6 metre Humber Destroyer which can handle up to 150hp.There are variable boat/engine packages available and have attempted to do as much research as possible including reviewing these forums. My dilemma is excerbated when I get differing views from the Dealers and the main UK importer as well.
Requirements are reliabilty especially after being at idle for say 15 minutes - instant response is required incase I need to move quickly from an impending tricky situation, economical, quiet at idle. Top speed is not such a criticality 5 knots differential will be OK. Reasonably priced servicing costs.
So the engine choice is Mercury 115hp 4 stroke, Mercury 115 Optimax 2 stroke or Suzuki DF115 TX 4 stroke
All views appreciated

The opti will probably give you the quickest response, the other 2 will be not far off and smoother, quieter and use less fuel at idle.

Whats the price difference?

I wouldn't say my Suzuki has the fastest response in the world. So as standard I couldn't recomend a 4 stroke. However if you did go for that type of engine and a quick getaway was important you could always put a different prop on it.

The Suzi and Opti are roughly the same with the Mercury 4 stroke more expensive by say £600

Hi Harry

Have to disagree with you on this one, comparing the Mariner 75hp Four Stroke or par with a Mariner 75hp Optimax on the same 5.5m Destroyer the Optimax was near on exactly the same with regards to noise at tick over and fuel in general. Ill be the first one to agree that the v6 Opti is a bit grizzly and throaty.

What price have you been quoted on the DF115? They have always sold for a lot more than the 115 Opti.

Why 115 and not 150?

Hate to admit it, but I agree with Mollers here. The 150 Opti is very good value for money, compared with most 115s

According to the list price there is a difference of £1500 between the Opti 115 and 150

The saving would be neglidgible if any and the residual would be compromised. 150 Opti's are good value, the only downside is that they're a bit noisey on tick-over.
