Last week I took the slug out to a choppy Wells bar and did some tests with a 5 hp Yamaha on the back and then did the same trip using the inboard


the test is on the beginning of this film - just the first 40 seconds or so - after that it is a longer bit about the outboard



chalk and cheese

I shall certainly miss the sound and water gripping ability of the beast

yes I am using a two stroke in an estuary - but it was not a 25:1 seagull - the yam runs at 100:1 and it was pretty close the top of the tide

Outboard sounds under propped to me, with the way the revs climb so quickly..

I agree; I have a Mariner 5 2-stroke which I think is the same engine ?

The engine Dylan's using sounds like it has a smaller flywheel than mine, and much smaller prop, I had to trim the prop on mine to get it to rev fully when pushing my 22' boat, not just my engine as a chum had to do the same with his, same engine & same boat.

I suspect too short a shaft for the Slugs' bracket too, then sticking an engine on the end is always a tad silly.

I don't think that was a very fair test Dylan.What horse power is the beast?

I had a 10 hp Mercury on the back of my pretty heavy 22' boat for 10 years & it managed to get me in & out of Portsmouth Harbour entrance on all occasions.It was a long shaft sail drive & I think it would have struggled against wind & tide on the most severe occasions but I never put it to that test.It did give me a sweet smelling clean boat that I think is pretty near priceless & my new boat with an inboard Bukh is hardly likely to do that :(
Sometimes I think we forget that our boats are supposed to be sailing boats & maybe you should stick to culinary experimentation :D

no tests are fair - not really

the Yam is only 5hp - long shaft - any lower on the bracket and I woulld have been worried about drowing it

the Yam came with Katie L and has done 20 years good service in and around Poole Harbour.

The beast is 10hp with a lovely big prop and a flywheel that would do justice to a tractor

I thought that while I had a 5hp long shaft available I would see what happened

both engines got the slug up to hull speed without too much trouble

although I would be unhappy about running the beast at high revs for so long for fear of shaking something loose

and unhappy about running the yam at full blat for fear of the impact it might have on world oil reserves.

However, for me it did confirm that the idea of dumping the beast and sticking with the slug using a 5hp on a bracket as my main form of power would not have been a great decision.

As for my cookery courses....

these are now being run on a monthly basis and are attracting not inconsiderable interest from some of the leading chefs

here are a few quotes from happy attendees

You are a stronger man than me.

I have a 4HP Mariner, basically the same motor as I understand it, and there's no way I could lift mine over the transom and down onto it's bracket, without me following it over the stern into the oggin.

The only real issue I have using my OB is the position of the controls. No problem motoring at sea, but less than perfect coming into the harbour, particularly if I need to go astern. I'm toying with the idea of converting mine to remote throttle etc if I can ever find the parts at the right price.
 
Dont suggest Seagulls to Dylan ...he doesn't like them!...:P
Even though we know the right one will outperform the Yamaha
See how rubbish it is when the prop comes out!
No thanks inboards rule
or an outboard low down in a well ...Good enough
 
like this then

I have tried eight different outboards on Katie L - most interesting

but PBO will not let me post the film yet - which is fair enough as they were paying me for the filming that day

of course, how a system performs in a flat calm is one thing - it is what it does in a chop that counts

I shall let you know as soon as I can

D

PS I am a great admirer of seagulls - it is just that using them other than at sea is thoroughly unethical

I think

you might notice the strap around the engine as I lifted it onto the boat

https://www.youtube.com/watch?v=bUWQgvHtgYo

it is one of these

http://www.saltyjohn.co.uk/motor_lift.htm


it offers all sorts of handy grab holds and gives you confidence that the cowl is not going to part company from the engine

very good thing - I now hang my outboards up in the garage

of course you could contrive something similar out of string/rope - but it would not be as good nor as comfortable in the hand

I have the small one on the little Honda

http://www.saltyjohn.co.uk/motor_lift.htm


I did not actually buy the devices - I swapped them for space on the website

but having used them for a while I would be more than happy to spend real money on them

I have bought a couple of small bits (well they were a birthday present actually) from Salty John and they are very useful (particularly the tiller lock [can't remember what it is really called but that'll do], it's a very neat and elegant solution). NB I've just had a look and it is no longer on the site. I guess people prefer their tiller mate and auto pilot type devices now. Oh well ta anyway John 'cos mine's great.

I will now investigate the outboard carrier.

Well spotted, Ian. The Tiller-Hand was a great little product but it's no longer on the website. At one point we were selling 30 a week.
Last year we lost the moulding tool (stolen) and had to decide whether or not to invest in a new one - about £6,000. We decided not to and offered the Tiller-Hand to any budding entrepreneurs but after a lot of initial interest no-one took it on.

Oh I see. What a pity but 6k is a fair bit to invest. If the tool was stolen does that mean that some scrote is making the tiller hand?
