4.1 High sided Dinghy.
Hi, I'm currently building the trailer for, and fitting out a Frewza 4.1 high sided tiller steer dinghy.
It is a standard "motor on the transom" model (not the optional pod and higher transom) but has a few minor mods....
Such as the transom/stern position 8 inches further forward while pontoons remain normal length (like an inflatable), and there are rear side alloy bins for dry storage, with the smallest Icy-Tek sitting in between (also doubles as the third seat).
There is a front compartment/seat against the anchor well forward, that holds a fuel tote), so a little bit of extra weight all up, but the fuel forward should help the balance as most dinghy's in my experience are arse heavy with the captain sitting at the stern. It's a very pragmatic and smart looking boat IMO.
Frewza have rated the dinghy for up to 50hp, but say 30hp should be sweet.
As well as occasional sea fishing it will be used mostly for freshwater including trolling for trout, for which I have traditionally used an old Johnson 4.5 hp 2 stroke auxiliary and it ticks over real sweet at the low trawling or trolling revs.
I am interested to hear the opinions of what motor would be best suited for the dinghy
(But for one particularly rocky dam I will keep the old auxiliary and swap it over, using it on it's own, as to plane on this waterway is just asking for an appointment with a slightly submerged rock).
But for the rest of the places I really would like to both troll and plane with just a single motor, as that would allow me to fit a comfy seat (as with only one engine, the helm position will remain static).
It seems that in broad terms a 4 stroke outboard is about the weight of a 2 stroke, and an auxiliary, combined.
Will a 4 stroke (say 30hp) troll sufficiently slowly and still get 3 up on the plane?
Would a 50 hp 4 stroke be too weighty for the slightly more arse heavy tiller steer? (I note previous comments that the Frewza's handle transom weight well).
What's the experiences of readers?
I like 2 strokes... is there a 2 stroke main motor that doesn't drive you crazy with it's lumpy idle that's suitable for extended trolling as well?
I am open to all Japanese or USA made 2 stroke or 4 strokes, such as Honda, Tohatsu, Suzuki, Yamaha, Mercury.
I would usually travel two up, but maybe 3 up on occasions.
Any advice and opinions appreciated!
I have all of the brands mentioned represented as dealers within easy reach for service.
Cheers, Captain Moonlight
