Now I have bought the trailer for my local use of the Honwave T38IE I am thinking of an engine upgrade to a Mariner 20 hp 4 stroke. I currently have a mercury 15 HP 2 stroke and a Tohatsu 10 hp 2 Stroke for local trips and was wondering what the benefite of the 20 4 stroke might bring. Remember this would be for trailering so not concerned about the weight of getting it on and off
I had my first blast out today with the 15 hp Mercury 2 Stroke with 2 people and the T38IE got on the plane very quickly and I got 17 Knots with the tide and 14 knots against the tide. I could cruise very nicely at about 12 Knots. I used 8.5 ltrs of petrol for a 18 mile trip.
I was wondering how others feel these figures would improve if I did buy the 20 hp 4 stroke
By my reckoning you'll get about 20% better fuel consumption and wot I find you get 2-3 knots more at top end per 5 hp now before anyone jumps in there's lots of factors that affect the figures but I've done a lot with my 25 and it seams that's about the norm of course you can play with props to get better performance to suit you boating
The bottom line IMO is stick with what you have you have a good turn of speed with and against current and crusing two up, you have other boats that fill the gaps this set up is a bit like gurnard's guppy it suits the quick no hassle get on the water set up and should be used in that way
