Hi Ian - what budget do you have for an engine? I know of a new tohatsu 30 short shaft going - its new but the dealer wants rid of it and may do a good deal - depends on your budget I guess - pm me if you like

Thanks Graeme
i have bought the 50 now so have spent my budget really . I would have considered a 30 but only if i could have tried one on the boat and been sure it had enough grunt.
A new 30 is a rare find

No Worries

Have to make my decision this weekend - got it down to 3 choices really - an SR4 Avon with a 40 in VG condition, an Avon 5.4 with a 75 Mercury - or go the SIB route and have a QS 380 SXD with a console fitted and a Mariner 25 - all very different and have their own pros and cons. Would be interested on how you get on with your new outfit - when will it be on the water?

To update this thread , I have the 50 tohatsu and lodstar 4.1 on the water now . There are no issues with overpower etc , it all seems to perform very well indeed .
Done about 41/2 hrs so far so the motor is still running in and I expect it will rev a little harder and run even smoother etc when its on the normal 50-1 oil mix instead of 25-1.

Quick bursts of Wot show about 30 kts , but the way it gets there is very quick , it literally fires out of the water to top speed as quick as you open the tap , you really have to hold on. I expect some adjusting of trim angle etc will improve things a little .

Cruising is very relaxed at 3-4k revs and it uses about 5-6 litres an hour at about 25 kts so plenty of power and light boat seems to pay off .

I really expected it would need a steering damper but there is no need at all for one so far , no pull or kick on the tiller at all even if I throw it about as hard as I dare . Maybe a different story when I start playing in the surf etc

Iam quite surprised at how quiet smooth and civilised the Tohasu 50 is , i expected a noiser harsher version of my yam 25 at least but its much smoother and quieter with a lovely snarl when you open it up .

Its a relief its worked out so well , I did have fears of the boat feeling unstable and chine walking and not being able to use all the power etc but its nothing like it . Even My 8 yr old daughter can drive it with ease .

Surprised the 50hp is so easy to handle, are you sitting on the floor to steer or have you got some kind of seat?

Any pics yet?

Iam as surprised as you . I really did expect it to be a bit of a handfull.

I have been out around Rame Head this evening and tried it in some chop and smallish rolling swell. hitting waves and bouncing about at cruising speeds its ok . I reckon if I drove it hard in that sort of sea then its going to get a little more challenging and maybe need some sort of damper , but i don't think my body will stick too much of that anyway I think just a bungee on the tiller will be enough

I sit on the tube most of the time , but the boat is just the right width to wedge yourself in sat on the floor .

It was just me and my daughter in the boat tonight so it was very light and we cruised at a steady 3500 rpm ish ( still running in ) the best bit was we used about 8 of fuel for a trip that was costing me about 30 before .

I will try and sort some pics somehow , ---Bob

Out of interest, how do you know what rpm it's doing?

Assuming it's by using a tacho, where do you mount it with a tiller setup?

Hi Ian-glad youre happy with your rig- i remember you wanting to get a surfcat-hard to find at a decent price eh.
Your rib probably weighs a bit more than my surfcat, but i think that you will find that running the std prop it will be a little under propped when going flat out- i run a worked semi cleaver 15inch powertech prop and it revs to about 5600/5700 (rev limiter cuts in at 5900)with 2 adults on board(about 45 knots)-i would imagine that you could run the same size prop.
If you do decide to get a higher pitched prop you will probably want a damper as when you jump out of even a small chop it tends to snatch quite a bit when the prop hits the water which makes you weave along.
The damper i use is the Mercades van steering damper with a tiller extension(same as the ones on the thundercats)from Mullacott marine, which is alot cheaper than the other dampers, but just as effective when set up properly. If you do decide to get these ill let you know what simple changes i made to make it much better.
