is this 100yam 4 stroke big enough for this boat? 2005 model on 5.5m savage defender.

If they were skiing with it,I would think so. There should be a plate on transom or console stating max. HP#of passengers ETC.

maybe you misunderstand me, i am keen to know if you think that the 100hp motor is not too small?
and if it is, what are the adverse affects of this?
 
Before you buy ANY boat you must insist on taking it for an in-water test to see for yourself if everything is workign, you're pleased with the performance and then ABSOLUTELY perform a compression check on the engine.

In my opinion, 100 HP is not at all too small for that boat. I am running a Yamaha F115 on an 18.5' Edgewater dual console fiberglass boat. My boat weighs 1,750lbs dry without any fuel, dual batteries, water, gear etc. (54 Gal fuel tank to boot). Fully loaded with 2 people I'm probably at 2,250 lbs. It was rated for 150 HP max. I opted for 115 HP for me is PLENTY - top speed is about 38MPH at WOT and finding water than I even want to open it up to WOT is hard to find. The boat you are looking at is aluminum and weighs about 500 lbs less than mine dry! HP that you can't use anywhere other than on a glass-smooth interior lake or river is worthless in my opinion. I'd bet with 100Hp on that boat you can cruise at about 24-25 MPH turning 4200-4400 rpm. Top speed at WOT would be in the high 30's at 5800-6000.

thanks for response mate, very helpful, i am intending to get a mechanic to go over the boat and motor, and then a water test.
just one point i wanted to make is that the boat in link is not aluminium, it is a fibreglass hull.
cheers

Yes.. I was just looking some more at the boat you are looking at and the manuf website and I couldn't figure out how they got those lifting strakes in on the hull of the boat you are looking at if it was an aluminum hull! As it is fiberglass, it probably weighs close to mine and probably a bit less than mine as Edgewaters are known to be on the heavy side compared to many back then (mine is a 2002). I would now guess with 100HP on that boat being fiberglass you'll cruise at about 24 MPH turning 4400 RPM (still within the max economy range) and top out around 34 MPH at 5800-6000. Again... still very respectable speeds and the sweet spot for 4-strokes and fuel efficiency is that 4200-4400 RPM range which you'll still be in. I say the boat is not at all underpowered if you aren't a speed freak. Give it a test drive and do let us know how it turns out. Cheers... Love you Aussies! These days you seem to be the most sane people on the planet! Except maybe you... What time is it there right now???? ; )
