yea fair one willk another litre of oil, all adds up but looks like the two smoke is available but either way hes looking at 50 kg lighter than the current rig which will be more manageable on the beach with two people pulling it.

Mainbrayce just emailed me

2k inc vat and delivery for the 9.8 tohatsu

Another 2.5k for the folding rib

So 88kg (honwave) and 44kg (current 4 stroke) v 26kg tohatsu and 48kg folding rib

Much lighter and I would love both set ups but I need to decide if I am prepared to spend 4.5k.

Thanks

The guy linked by Chipko and used by Mickhitchuk is 500 cheaper for a new Tohatsu 9.8....

Plus a new Honwave 3.8 air floor (48kg) for 1000...

Now your package is 2k cheaper. Worth a thought??

Yes, sorry, that would obviously be a better option

Be aware that the Tohatsu 9.8hp is unlikely to plane that SIB with 2 fullsize PAX plus kit.

I did wonder if it was marginal but Max had great success with the 9.8 on a 3.4m air floor Zodiac with him plus his lad (perhaps more folks too at times).

Here was me thinking it would do it fairly easily....

That is based on my 15hp planing my honwave with 4 people - not very scientific I know, but it would be a massive weight reduction with a lighter boat/engine and 2 less people

as willk says a 9.9 probably wont do what you require if you scale down what gurnard is saying with his 2.75 & 6hp rig your going to be somewhere similar with the 9.9 and you have paid 4.5k for the pleasure.
current rig 132kg
desired rig 74kg with 9.9
go Suzuki 15hp 4 stroke @ 44kg 92kg total thats 18kg heaver 9kg each two people pulling up beach and will plane engine cost 2025 new.

cheers
just noticed you have a 44kg outboard just the frib then sorted.

Yeah that's actually probably the best option in terms of weight saved v money spent

Thanks

You do well in my experience to plane the 4m with 4 folks and a 15hp... unless of course two are children. I had the 3.5m version and with two adults, two teens and kit it needed perfect conditions to plane with a 15hp 2-stroke.

Edit: As others have just said above I wondered if just saving the weight on the boat would be enough keeping the existing outboard... what make is it?
