How do you find the 9.9hp? I've come across a 9.8 tohatsu which is another option... any feedback on the Tohatsu would be welcomed.
Before I got my current SIB I had an Avon S250 (70cm shorter and 15kg less than your S300). With the 9.9HP and 2 onboard it would plane quite happily.

My current SIB is a quite a bit heavier than yours. It would still plane 2 up with the 9.9HP, but it took a good few seconds to get on the plane.

Now with 15HP, it is noticeably quicker to plane.

I don't have any experience of the Tohatsu 9.8HP, but a browse of the forum would indicate that they are well thought of.

Cheers

Chris

Loco - All these items were bought seperately from the the engine itself.

Over here Yamaha do a kit, which comprises the throttle/ gearing control (complete with key/ ignition etc - not used on mine as it is a manual start with no power trim/ tilt) and mounting kit for the engine. They also do another kit comprising the steering cable and engine attachments.

Worth noting I also had to modify the internals of the engine slightly - shaving a small piece of metal off to allow the throttle to open up fully from the cable - this is probably not necessary if the engine is intended for remote control.

I never intended to mount steering on such a small RIB but I found it a bit hairy at full throttle on full lock on the tiller (necessary to dislodge passengers from the ringo!) - a few high speed ejections from the boat convinced me that the way I drive console steering is a must!

Chris - I'm leaning towards something around the 8-10hp range, thinking forward to buying a bigger RIB it would make a handy Aux - 15hp probably a bit on the large size. That and given the age of the Avon, I don't want to over stress her!

The RIB can be the pocket rocket while the Avon is going to be a more practical, fishing/ light diving/ snorkelling craft...

Sounds like a good plan

Hi Inflatable J.

The hardware to secure steering cable to engine comes in the Yam 60 HP kit, as it's a remote version, so ok with this issue. You were inquirining about Tohatsu 9.8, this engine is completely different as the 9.9 model, wether 2 or 4 strokes versions, don't have an opinion on 4 strokes, as we only sell 2 strokers models which are excellent.

Happy Sibbing

Loco,

There's a good chance your throttle & gear cables on the 60 will go through the front of the case & attatch to the linkage under the hood.

The external fixings were a bit of a historical thing on the "in between" sizes - i,e Horsepowers that were big enough to sometimes need remote, but could also be used on tiller. (e.g my 1972 Johnson 25)

These days there tends to be a removable panel on the front that is replaced by a giant rubber grommet that takes cables & wiring.



I-J.
Just a thought, but if you are out fishing, the wee 5Hp might be a good trolling / spare engine? - Assuming you get an old premix 2- stroke, it won't like idling for too long before it oils up.

Hello

your avon must to be an 70 model or maybe older i own the s400 (a little biger than yours)1969 and have the same old avon logos about the motor i use the 15 hp mariner and she runs well, i think the weight of the 9.9 and the 15 are almost the same i recomend to you the 15 hp, all avon are hypalon made, to patch mine i have use the weaver two parts adhesive (its the onlyone i can find where i live). about the boards i post the picture of the 4 boards and the 2 side battens needed to complete the floor, i will send to you as soon as possible the instructions to assambly.

cheers
Sant
