Bilge Rat,

For your information the 14" Prop for me was worth every penny. On my old Merc with a 4 Meter Sea Rider I am now getting 30 Knots at 5500 Revs. Thats in a slight state of sea with 1 to 2 foot waves quite close together (Or so it seems when your belting along). I can still accelerate and pushing the throttle wide open the engine won't go past 5500 Revs. With the 12 incher it would Rev higher but you weren't going any faster and max speed was about 26 Knots. I actually managed to get the whole boat out of the water a couple of times which doesn't normally happen, either because I'm too scared or too slow.

So I guess each extra inch of pitch gives you an extra 2 knots on our size of engine.

I also had to alter my trim and this gave me some extra speed as well. I only did this because my mate has the same boat and we could all see that his was riding much better in the water. His engine was trimmed out farther than mine so I gave it a try and it worked. Initially I trimmed out too far and I was flying everywhere and cavitating on turns, but once I'd gone in a notch it now looks and rides the same as his.

Guess the old beast just needs a service now.

I shall be keeping a look out on E Bay for a 15 " prop and if I can pick one up at the right price I shall go for it.

Incidentally does anyone know if a 14" Stainless prop will give me some improvement over the alloy prop.

Hope this helps Bilge Rat,

Regards Nick R.

Ha Ha, Nick.....I had a 15" prop onboard on Sunday, could have followed me to Haslar and borrowed it if ya wanted, can't decide to sell it or not but I recon I'll only use it for a spare or if I've a heavy load onboard.

What make outboard you got? You shot off too quikly for me to have a look ?

Andy

Hi guys,
If I may add my tuppence...
My 90 had a dreadful pull to one side through the wheel and adjusting the anode skeg over cured the problem. As mentioned its surprising how much difference it can make. I could also do the hands off now, its so light. I have a 19" on at the moment and wot pulls out at 5000.

And by the way its not the size of your boat that count its the motion in the ocean...

Hi Andy,

Thanks for the offer. But I think after 60 HP the props are different. Probably bigger.

The engine is an old Mercury 50 HP Blue band, painted in good old MOD grey.

Its just to see me through until I can make my mind up which boat to get next.

We had some fun yesterday, just wanted to get a blast with my new prop and I'm well happy. Got a few little tricks to do with it to see if I can improve its performance, then I've got to coax a year out of it until I change boats.

Hope to see you around in the Solent again.

I tell you what mate, I knew that was your boat from about half a mile away its so distinctive, the colours don't half stand out. I like the new shiny engine as well.

Regards Nick.

Thanks for your comments Nick, I only installed Hydraulic steering last week and the extra turns from lock to lock take some getting used to, especially when manuvering. I think I need one of those spinner thingys that attach to the spokes. It does make it much more pleasurable to drive now, although I couldn't open her up too much with Dad sitting behind me, he is 78 years old! Did mange a top speed of 35knotts though .

Let me know when your next down and we'll meet up.

Andy,

Due to the fact that I have to work the next two weekends my next trip out is likely to be to RIBEX on the saturday. A few of us are going on RIBS and shall be spending the whole day drooling over new boats, eating fine food, having a few beers and trying to prise some 'gizzits' out of the stall holders.

I've got a little bit of work to do on my boat next time I see it. Fix down the rubbing strake at the front, tinker with the engine and fill it with fuel.

No doubt I'll see you round.

If you want to be certain to catch me just look out for me every weekend in the Hayling Bay area one hour before high tide and two hours after it every weekend. If its an earlyish tide I go out on the back of that and come back in the evening on the next tide.

Alternatively call me on VHF using my MMSI around High Tide. That is if I can hear it over the old beast. Callsign "Seaspray".

We normally end up going over to the IOW but I'm trying to drag them all down towards Selsey Bill and things East. We also like the Sandown area. It has some nice pubs.

Regards Nick

Sorry Olly

Just seen this thread, if you remember we did all kinds of things while we were comming back from the Pub (only food) even leaning right of the side made very little differance to the effect, so the consol is not the problem, belive me.

The idea of torque steer i think is also not an issue either, as it was very hard to even get near full power, we were only running at about 35/40 hp, so i feel this has got to be somthing else, did you remove the Dolfins and try it without them, as it felt fine while the hull was in the water but seriously scarey out, even turning the steering in the oppisite direction did little to correct the learch to Stbd, you dont realy need them on there as you have enough power to get on the plain

Ian
