Honwave T40 AE3 Video Impressions

[smallribber]

We bought this sib last year but have only just got round to its maiden voyage. We have a 20 hp 4 stoke on the back. This is a very spacious and capable sib but it is a heavy beast and we feel best suited to trailer boating.

The boat performed very well. I need to tweak the linkages a bit to get the best out of it. The boat is on the extreme trailer that was effectively designed for this boat

I think I can scale up my experiences of our T35 to understand what the T40 would be like. Tank of a SIB, well made, roomy and stable. Lovely big flat floor. Don't know what the transom is rated to but a 30hp might be worthwhile to get it moving well. Oh just looked, rated to a 20hp same as T35, I'm surprised.

Blimey, always thought T40’s were rated at 30hp/86kg max.

Wonder why it's only rated for a 20hp? I know the old T40 was rated at 30hp, I'm sure that's what Highland Haggis had on his before it got nicked (anyone heard from him?)

You mentioned the throttle being a bit stiff, does the old Merc have a throttle grip friction knob on it like the newer Merc efi has, could be a simple fix if it has.

IMO it looks a tad bow heavy or does the OB need trimming out to the next hole, think your overhead drone shot (@ 4.00) highlights what I mean.

They were originally rated to 30 hp and on the plate many still say 30hp. The published info now say 20hp however. I know several that have 30hps on them

Yes it does have a friction grip nob and I will look at that tomorrow. Things were all a little rushed for various reasons. I also believe trimming 1 hole out is a good plan.

No drones used in this film only Insta 360 X3 and a very long pole

I asked the guy on the Honda stand about the rating and he showed me the Honda 20 v the 30 and it is one heck of additional weight. The Transom is mighty however. Once I have the Merc 20 set right I actually think it is plenty of power. I think trimming the outboard 1 hole out will also help the slight splashing we were getting over the sides.

Still one excellent boat but only for trailer launch IMHO.

[smallribber]

I had not actually looked at the plate on the T40 so this morning I took the photo below. It clearly states max engine size as 30hp with a massive weight of 90kg. It also shows it is made by Sun Selections Co in China. No surprise there.

So if it says 30hp on the plate but Honwave say 20hp... Where does that leave a buyer I wonder. This is a very new one only bought last year ?

[smallribber]

Thanks to Steve and others I have now adjusted the throttle tension on the tiller and oiled a few things and the outboard now goes into gear much better.

I have also adjusted the trim to the 3rd hole and the angle of the outboard now looks a lot better. I was very happy with how the boat performed but I think with these changes it should be loads better. Retest soon

[Fenlander]

Oh I'd happily go by the data plate which fits in with a gut feeling a 30 would be about the right max HP for a big alloy floor SIB on a trailer.

The other interesting thing is that one of the main points of these big sibs is to keep them on a trailer with the engine on. The 20 is 53KG but the 30 is more like 75KG. I must admit I worry about that bouncing about on the trailer when towing particularly on the poor roads we now have in the UK. I am thinking a 25hp 2 stroke would be an interesting match

It moves pretty well with the 20 to be fair. I really like these boats but as you mentioned, its weight might be bordering on unmanageable without a trailer.

Am I mis-remembering, or did you have a 15 Yamaha 2T also? I wonder how it would be on here compared to the Merc 20 4T. A little less power but a lot less weight too.

Since getting a RIB, do you think it's worthwhile holding onto a trailered SIB?

Now you've opened the floodgates.

What of course it is. I actually have 2 Ribs and 2 trailer Sibs and 4 other roll up sibs. Sibs are very different craft and great fun. They can go places and be used where Ribs cannot so easily. They are very inexpensive and exhilarating.

If you have the space and can afford them have as many as you can. The only way to waste money is never to spend it

I have indeed got a 15 hp Yam and this very day just returned from picking up a rather nice 25 hp Mariner 2 stroke that I think can be upgraded to a 30hp with a simple gasket. That is actually 2 kg less than the 20hp Merc

[smallribber]

I was thinking about 30hp but did not want all that weight on the back. So I found this beauty just 10 miles from me for £1,080. As I said I think it can be upgraded for a simple gasket to 30hp and it is in rather good nic. Almost a minter. It is also 2 kg lighter than the 20hp Merc.............. And my fav it is a 2 stroke

Good old Seamark Nunn, they often have the best selection of used OBs and decent prices too.

Slightly different cowl logos but is it the same as Donny's old one? If so service guide here by the man himself.

Yes I think it is indeed the same as Donny's. I am sure he would by devastated by my step backwards. The weight and power I think will suit my application just right especially with the 30 hp upgrade

[smallribber]

I think this quite old thread on the upgrade will be helpful as well as Donny's excellent guide

I hope it works out, you will soon know pulling the carb off yours but I think that guide is for the Japan made Tohatsu badged Mariner. I reckon you have the Belgium made model.
