i fished a 100 days out of billfisher that had twin 165hp mercruisers
a mate of mines got one with twin 15o opties and hes stoked
another mates got twin 250 etecs and said it wasa desth machine
if i saw 4 strokes on one id cry
4 strokes are for oyster and mussel punts dredges and commercial taxis
2 stroke pwer and fuel economy miles better
the only ones banging on about 4 strokes are the people that shelled out 1and a half times what a normal outboard costs and you have to take out a loan to get them serviced |
Good one mate i might pull the v8 4 stroke out of my car and drop in a 250hp 2 stroke.

| .....er....what has that got to do with the comparison of the two boats mentioned ? But yeah, I can see there is a tendency to over-power boats, most of the time conditions preclude its use anyway. I suppose more efficient engines has led people into bigger horsepower. |
Didn't I read somewhere the current 233 built here by Edencraft is some 300+ kg heavier than the early HH models? |
At least 300kg! In addition, the HH233 was also built heavier than the original Formula/Thunderbird 233.
This explain in part why there is a tendency to run more power these days.
Having said all of that, quite a few of those produced by EC over the last few years are fitted with twin 175hp Suzuki 4-strokes. They perform reasonably well.

| The switch from I/O to outboards means 300kg+ extra hull weight would still have the outboard boat lighter, though. |

That's fair, however the EC is approaching 500kg heavier than the original Formula Thunderbird 233 (bare hull) out of the US which worked well with a pair of 165's.
To put the weight difference between the US and Australian built boats in to perspective, it is not uncommon for people in the US to repower a 233 with a single 225hp/250hp outboard and achieve speeds of 45knots at WOT.
Also, back in the day boat fit-outs were very limited.
These days boats are loaded with all sorts of stuff. Take Opti's 233 for example, there would be an additional 500kg plus in fit-out alone over a more typical EC233 which is already approx 500kg heavier than a US built 233.

"Typical" west US coast boating doesnt see the kind of conditions we fish in here, though. To them, generally speaking, a lighter boat is no ride disadvantage

| I looked around for one with a single 330 hp M/cruiser years ago, but couldn't find one at the time, still think it would have been a good option if you are happy to cruise about 25 knots, fuel wise. |
