I am looking at removing the 'jersey keel' from my princess and one guy is suggesting assuming 12mm bolts countersinking top and bottom of holes and filling with thickened epoxy then matting over the inside, does that sound like a strong repair to you? Bearing in mind I will be using for fast sea work and often in quite lumpy water.
I am also thinking of removing the 2 anodes from the bottom of the hull and refitting to the transom to further reduce drag, does that make sense?

I modified an old Triumph spring compressor to get min out on Silver Gem. The 'blue' bit is a length of scaffold pole sliced in two.

I might just get the yard to do it yet as I would like it back in the water next weekend but if I do myself I don't plan on removing the shafts, I have a very convenient piece of 1 1/2" ID aly tube in my shed to make a drift from (run a cutting disk down the sides) and some 10mm steel plate at work to make a slotted puller from, a length of theaded rod is easy enough to get hold of, and my manager is on holiday next week so can get away with a good deal of homework.....
Just need to find out if the OD is 2" or 2 3/8" on the bearing.

Naaaa Dave, stainless steel shrinks in dry air so your shafts have shrunk. You need to build a bund around the props and fill it with water, trust me hahaha, I wouldn't dream of misleading you!
On a (slightly) more serious note - are you dropping the shafts out to change them? Much easier to do the job that way. Tip - borrow an impact screwdriver to remove the grub-screws.
Guessing you might not have done this before there are some useful tips on this page, scroll down past all the Cutlass/Cutless garbage!
http://www.pbase.com/mainecruising/replacing_a_cutlass
Hw waffles on about scoring the inside of the P-bracket as if you repeatedly change bearings his way you'll weaken it! That is just the marine equivalent of being PC - it has no effect on the bracket if it is scored, and you'll be unlikely to ever change the bearing again for years.
The joy of this method is you don't need a different puller every time you do the job, not that you would unless you run a hire fleet.
Just get a decent hacksaw, some spare blades, some WD40 or Plus-Gas, an impact driver and correct end, couple of washers and two M16 nuts and a length of M16 studding and a bit of grease.
You're only other concern to keep you awake nights for the coming week is whether or not the boat is chocked high enough to get the shafts out. It is not of course so you'll need a couple of yard crane lifts to lift the stern once you've undone the inside couplings to quickly slide hte shafts out and later to stuff them back in. Don't forget to loosen right off the stuffing boxes inside before re-fitting.
Some shaft couplings do need a large chain wrench to hold them and a C-spanner with a long tube to undo the c-nut - you'll need to look at yours to see what is required to free them off. If the C-nut type that squeezes "fingers" around the shaft check the required torque settings for refitting - it is very high - and you don't want the shafts and props sliding back and hitting the rudders when you go astern!
Seriously Dave - do your homework first!
Finally living the dream!

Another glitch, need to replace a cutlass bearing, not sure how I missed it as rattled the shafts around and not noticed till one of the guys from the marina pointed it out today, do they shrink when they dry or something?
So next job is to find out what the outer diameter is and get a bearing and make a puller, might just do both sides while I'm at it.
Have glassed over the insides of the repairs now just to do full belt and braces job, more dust, more epoxy all over me, such fun.....

Some more piccies with new anodes fitted and antifouled, got to finish replacing the wood on the bathing platform with wood plastic composite (maintenence free for lazy gits like me)and finish replacing the seacocks and scoops as the old ones were getting a bit corroded, next weekend hopefully and get it floating again the weekend after.

Now you see it...
Now you see a bit of it...
Gone!
Now don't they look pretty, repitched to 18x17 and balanced
and generally sorted.
The front mount needed some reshaping as it's been built up in front I assume to allow for a bit of rubbing on the bottom when drying out, should be out of the water at speed anyway, looks better than the 10mm step that was left when I took the plates off.

Mounting plates now off, I weighed it at about 90kg of scrap stainless steel not including the bolts/nuts.
Apart from some reshaping around the front mount the rest look pretty good underneath, the front one has had some building up done probably to act as a sacrificial wear pad just in front of the bar.
Looks to have been painted with gelshield before putting the mounting pads on as it's green under there.
One of the guys at the yard said it should improve my mpg so I pointed out that a 1mpg increase will be close to double what it's doing at full throttle now.
Hopefully get up there next weekend and get the holes filled and hull smoothed, will probably brush a coat of epoxy over where the plates were before antifouling.
Timing was good as anodes have completely gone so I guess I have some stray current going through the bonding, could be the ferryhouse's electrics as I often plug in there, may take shore power earth out of the bonding circuit.

The big bits are off and it's now sat on blocks waiting for me to remove the mounting plates, a couple of the bolts had weeped a bit but all nuts now exposed ready to be undone.
That centre rail was 8mm wall thickness and bloody heavy, only killed 3 9" disks though.

Good luck with the mods, Dave. We demand piccies, especially if you cut off the wrong bits.
I'll be sure to stick a quid in the next RNLI collection box I see in preparation for your shakedown run....

Surprisingly I don't drink that much on board and don't tend to carry much, we always aim for a pub where possible and don't drink at all on sea runs.
Once in a pub it's a different matter, I know where to get good lates on the broads....

I'll be interested in seeing if you get the performance enhancement you're looking for.
Still think from your comments you need to look at adjusting the maximum down angle of the trim tabs so you have a little in hand even when the boat trims level. It isn't hard engineering wise to extend the end of the coupling yoke of the hydraulic ram by adding a piece in and it will give you some options once you are back in the water.
Good luck with the mods anyway.
