Gaz

Thank you so much for the very kind offer :oops: but I do not really know. They are self tapped into the hole left by snapped button/switch.

I can let you know next time I am down there, if that is ok.

Many thanks Mark

Sounds like you are heading in the right direction wi the shift, you may have gone a bit too far, turn the barrel nut back one turn at a time, and check to ensure that when in neutral that the prop isn't rurning!! Can feel like its olk, but you may still be in gear, which can be interesting in a marina!!

Prop - oh dear, you're not having much luck are you
In theory you can change in the water, I did it once on an outboard - flippoin hard to get the leverage when standing in a muddy gloop and the boat keeps moving away from you, you need to make sure you don't drop the nut or lock washers etc, let alone the prop, f its not been off for a while it could be a bit stiff to get off the shaft. The vibration sounds like you have taken a chunk out of a blade or two, try not to use it as it could cause damage by the eccentric load on the gear box. Props are easy to repair if alu. I have a ss now and think it is much betteer. Mine is a 19 in pitch and quick off the mark. But top end not as fast as it could go with a 21 or 23 in pitch, which would be slower to plane but faster to end

Don't you just love boats!!!

Hi Baasboat

Prop was off in May during service and anodes changed. Yep, there is a sizeable chunk out of it on one and a bend on other. I wouldn't mind but I was doing it by the book and know the hazards of the area. Just my kuck to be there one day before the dredger, who incidentally I watched the next day!!!

I plan on coming into my mooring stern to and trimming right up, so prop is just proud of the water. Needless to say, I haven't got a bloody clue how to change it :oops: or what size it is.

We don't ski (remember I am a sailor really, so this is all alien to me), so top speed is more important than getting out the hole. I hear people reporting 50mph out of this boat/engine package but 40mph is absolutely the limit for me, fully trimmed out.

Will a higher pitch not add strain to the gearbox? Because that'll be the next thing to go.

Wish I could just buy a new one but I could not justify (or afford) £40k + for a boat this size.

Despite it all, I still love boats and the water. I am working on the fact that once I have rectified the snags (and I am fussy about things being right) that I will have a boat that is mine and one I know every quirk of.

I have to say, she is the smoothest boat I have owned, even in a chop. One thing I would never be without now are trim tabs, fantastic.

Just wish boats were cheaper to run, sure some things are stainless steel but in general they are car parts in marine packaging = 3 times the price.

Thanks again Baasboat

I would sit on the pontoon and dangle your legs on the water, get the close to you, then use a flat bladed screwdriiver to prise up the two or three locktabs on the locking washer behind the nut hoding the prop on - that's dead easy to do.
The you can either put a bit of timber between the prop and the cavitation plate to stop the prop turnioing whilst you remove the nut _ or if have a good grip you can doit by hand, just don't slip or you may start the engine and have some stumps where your hands used to be, will need a bit more than savlon
You need a big spanner (you can buy a plastic one that floats - which may come in handy) or just buy a big socket and use a normal ratchet to undo the nit, the first turn should be fairly thight, then it will ease as you come up the shaft, just don't drop it when you get near the end of the thread, use your fingers for the last turn.
Take off the nut and the locking washer and put them safely on the pontoon. Now gasp the prop with both hands and start pulling slowly, if its been off a few month ago it should co£e off ok, then take the thrust hub _ a bif thick washer - note tjhe bevel direction as it comes off, so you know which way to put it back. Then get your prop repaired, you can check the pitch by looking at the numbrrs stamped in the prop hub, look for the one near the P

Hope that helps

Regarding changing the prop

get someone or a few sat on the front as far forward as possible.

drive up in trailer position
Peel up lock tabs (easier if there the ones with the holes in)
27mm socket for the nut
Be careful when you remove the prop from the shaft as the square hub and or thrust washer can fall out (ok when on land not so over water. ask me how I know :oops: )

Picture of all the bits

If you can tell me what size screws they are I should be able to make a couple of levers with the same thread so they just screw in

How do you know Gaz? :mrgreen:

I might just bite the bullet and get her lifted out. This way I can also make the adjustments that Baasboat has suggested and no risk of losing bits off the prop.

Regarding the screws, the port tab was already screwed in like that and when the starboard tab broke, I just grabbed a screw that fitted without even thinking about it's size. I will find out though. :D

Sounds tight fisted (and I'm not) but £85 for a switch is unbelievable. Perhaps if everything else was perfect I would but my luck (and with limited funds) if I buy a new switch, something else will break! :(

I will keep you all updated.

NEW engineer has today identified my shift problem to be a faulty switch - well done all :D

It is the new type so doesn't have metal bar that can be bent. Said ordering one today and fitting tomorrow, I will be amazed if he can :shock:

Thanks all, will update when fitted.

New switch fitted and problem solved. Had two great days on the water, albeit the weather was not ideal. :D

Credit were it's due, it was bassboat who ID'd the interuptor switch, I was heading for shift adjustment.

Well done that man! :D

And I very glad you're back on the water!

Glad you have got it sorted now and been able to hit the water, how did you get on changing the prop, did you lift it out in the end or do it off the pontoon?

Thanks to all helpers, sincerely grateful :D

Prop was put on by new engineer, on pontoon and within 1 hour of first request. :D

Amazing!

Now - how can help improve the weather :mrgreen:

I went out just in Cardiff Bay on Saturday and it was gloriously warm and rough even in the bay. Once brother and sister in law arrived (first time on this boat) it changed for the worse, although we still went out on Sunday and Monday albeit a lttle rough.

I am off work until next Wednesday hoping for a weeks crusing but the weather is *beep* and the forecasters are changing their minds on an hourly basis, so just going to do a few odd jobs. No doubt next Wednesday onwards (back at work) will be 20+ degrees :evil:
