Surprised you can still get a new 100A, I thought they were all 100B's now (1.5L block).

Personally if you go the df100A you may aswell get the 115 or 140 in my eyes. Same weight why not.

DF100B is a good little motor from the minimal 8 hrs use ive used it for. Bit thirsty at the 6k rpm mark chewing 33l an hour.

Cant comment on the honda. We didn't select it mainly on price factor and the 95 wasnt a big deal but less than ideal to be fueling depending on where in country

. 45 magnum by skeltoncraft.. Is pushing 42mph and theres bugger all difference in speed between 5500rpm and 6000rpm (Hull speed is tapped out I believe)

We do get 29mph cruise at 12.2l an hour at 4100rpm

Honda is the better engine and cheaper to service, ive sold and serviced both so know them ' inside out ' Hondas are quieter and run the cam chain at the top of the motor rather than the bottom. Honda have adjustable valves for valve clearance and easier to work on. 7 year warranty no brainer.

90 hp DK5and 4 XRTA .LRTA,JRTA from 2007 has a timing chain the part no is 14401-RB1-003 some 100hp also have the chain.

As for RCs comments above he obviously hasn't worked on many new suzukis as valve adjustment is easy they run an oil bath timing chain also swing a bigger prop run on 91 like a dream. Happy to answer anymore questions. Cheers

yeah im going new.

I’ve just bought a new Seaforce 530 Ute and went for the Suzuki 140. Same weight as the 115 and it does go really well, no need to play with the throttle. It was only a couple of grand more as well. I don’t think I would want to go much less having used it. Worth considering.

I checked with Ric first and he said it was all good, I’ve only just run in the engine so still playing with it but it does go over 40 kts. Top end speed is not really the goal but there is plenty of power to go through chop and to carry a bit of extra weight. It handles really well. I think the max engine weight is 200kg and the Suzuki is about 180. I did initially consider a Honda but they are too heavy for the same H.P.

just worried out the weight and motor being 25% larger

5.3m hull real terms about 20kg...think a couple 9L buckets of water with a few shellfish in would make a significant difference?
 May at rest.. 1/2" lower in the water at the stern.. at most.. on the plain.. zulch.


Personally if you go the df100A you may aswell get the 115 or 140 in my eyes. Same weight why not.

 my thought as well.. what is the max spec?
 I would imagine the boat fully loaded to come in around 900/1000kg gross weight on the water going on similar boats in my data base... that would put 115hp nicely powered... and handle bars nice as well if things got a bit dicky

 140hp thats good to nicely power around 1200kg

90/100 puts it as min to just over min.. keep in mine 4S produce a little more hp than usually stated

 go the max for the hull..if you want the best hull performance in chop, on flat and economy and overall comfort.
