Hey Francesco - wow!!! - this is my wife's late father's boat (and a lot of the reason I own a Bertram 25 now). I know the family you purchased her from, my wife's family also have a house on Santa Maria. I've been out in Eta Beta a few times, what a boat but it was in dire need of a lot of work. Do...

Thanks all. I have managed to unearth the manual for this drive, or part of it at least. The drive is from 1996, at which point there was no "X" or diesel version of Mercruiser sterndrives. A very interesting point in the manual: " Normally, a 150rpm change exists for every 2 in. change in propeller...

beachbum

Thanks everyone. I can get a 25p x 17.25 dia to try to free.

I'll give it a go and if it doesn't reach revs then I suppose I will know if a 23p is going to work or not, i.e. if the 25p is miles away from making 4000 then there isn't much point in trying the 23 either!

beachbum

Hey all, So nearly 2 years down the line, I'm still going strong with the '25. However I've got a dilema which I know someone here will have the knowledge to advise on. My '25 has a 320hp diesel coupled to a Bravo 2 leg. After much scraping and cleaning, I finally found the all important data I was ...

beachbum

Yeah that's it, it's a B2 alright. It's definitely geared up to spin free with less load and I'm sure there are another 5 knots available if I can get the leg set up properly. I've looked at the 3X although it's going to be out of the question for the moment ($€£) - 2nd hand units here in Europe jus...

beachbum

Thanks captbone - these are the best I've got. Engine is a 4.2 litre Mercruiser diesel, 320hp. 3900rpm with the limiter at 4000, she reaches 4000rpm no problem, and can do so even when a bit dirty. https://hosting.photobucket.com/images/r587/Beach_bum_/DSC_1901.JPG https://hosting.photobucket.com/im...

beachbum

I've tried measuring the ratio myself and I think it's 1.65, the prop I'm not sure but looks to be a 21" diameter

beachbum

So on we go. During the time she was in the water from March 2021 to July 2022, there had been a constant drip in from the sterndrive transom assembly. I knew my repair attempt on the steering shaft hadn't worked as the area the steering seal sits in, was too far gone. New transom assembly required ...

beachbum

Where did you move to? Are you near Piombino? I thought you were near the sea but can't remember where exactly... I'm in Genoa (again apologies I don't check this board as much as I should!) Hope you're having a decent winter, it was like summer here until end of November then winter came in 1 week

beachbum

Hey Yannis sorry I don't check this forum as much as I should... Fishing it'll be bream, flatfish a bit deeper maybe. I don't really know much about it around here but I fished loads as a kid so it's something I really want to get back on the water for! Just moved house so there won't be much skiing...

beachbum

Yannis, Yes I'll get her back in just before Xmas and stick a few photos on my thread too. Mainly just to get out fishing, there are plenty of 18°c days with flat seas so I'll get the kids out too. Good call with the smaller boat, I forget what it's like finding a berth sometimes! Went on the new 35...

beachbum

Hey Yannis, ...negativo! We didn't do a lot last summer. Was operating a San Lorenzo 118 and the Pershing 108, though the SL sold about a month ago. Yeah I had my eyes on the forecasts, looked like a very windy one your way. The 25 is inside the warehouse in the yard, had all the antifoul removed. T...

beachbum

I've worked on Sunseekers, San lorenzos, Pershings and various others....the fibreglass is as thick on any of these 80-130ft boats as it is on my 25. In fact on one of the Sunseekers, it was almost certainly thinner

beachbum

When you think of what rolls off the production line today, it really is amazing. Boats barely last 20 years. Mine is now 53.

I've just taken all the old antifoul off back to the gelcoat (and in many areas, resin), 3 coats of epoxy, so I'd say she's good for another 10 at least!

A captain I used to work for on a previous vessel painted some parts of an engine with awlgrip, it did begin to turn a bit brown shortly after

beachbum

In terms of chines, mine are just touching with a full tank too, but a single diesel sterndrive. Having said that, I've stripped off all the old antifoul back to gelcoat (or in some areas where there is no more gelcoat....resin) and the hull has been sat in the yard drying out after the hottest summ...

beachbum

I'd probably go for it to be honest

There's a Superyacht chase boat up for sale in our marina with 2 x yammy 200s that have done over 5000 hours (the vast majority at 4000+ rpm) and still sound like they're new

beachbum

Of course, I talk with the boat all the time. Doesn't everyone? Recently it's been swearing more than talking, "you ****ing piece of **** why does nothing ever work no matter how many ****ing hours I put in...!" This is the problem when the day job is a superyacht and the hobby is another boat, som...

beachbum

Seems way overpriced until...

€110k!

https://www.subito.it/nautica/riva-bert ... 773982.htm

Granted, it's a Riva and it looks immaculate, but €110k ($124k US)

Beginning to think my diesel 25 for €10k might have been a good investment

beachbum

https://m.youtube.com/watch?v=BurX5_WEyNg

Yeah I agree, the 2 Tasmanian guys who stuck a pair of Yamaha 200s on a 25 FB saw 40 knots. 50% more hp for 5 knots...

Though can't argue with the work, looks fantastic.

beachbum

Hey Greg, I have a 25 SF with a single Mercruiser diesel 4.2 320hp from 2007 on a Bravo 2 leg from 1992. It is slow as I'm sure it's propped wrong (or there is the wrong gearset in the upper part of the leg). I get 25 knots WOT but she goes over the max rpm. I think I could get around 28 knots by: 1...

beachbum

Nice, I'm envious!

beachbum

Thanks Carl Yes I found the name of a prop specialist near to me and I'll be investigating in the winter. If the rest of the boat was anything to go by, there will be 20+ years of antifoul accumulated on the hull. I simply didn't have time to take her back to the gelcoat last winter but I should do ...

beachbum

Cheers Cam. Boat is filthy underneath at the moment so it's not worth even trying until I get her out and give her a spray. For info - I was a bit off with the chine vs waterline. Port side sits about 10mm above the waterline whereas stbd is 10mm underwater. She's always leaned a little to stbd, whe...

My good god that's beautiful

Thanks all Thinking more or less along the same lines as me but good to know that she might be a bit heavier, I guess this is down to the 460kg (1014lb) engine. Add fluids, the leg and transom assembly etc and it must be over 600kg (1300lb). The chines are dead on the waterline at the aft. The prope...

beachbum

Thanks Carl - a bit of Semco on the teak and a few hours polishing makes a huge difference. Yep I'e considered having the prop cupped a bit. It's also got antifoul on it which must effect prop slip etc, really not that smooth a surface in contact with the water. I'm not bothered about crazy speed at...

beachbum

Just an update for anyone interested. Had a good few days out on the B25 so far. Only 1 real issue - the engine stopped when coming off the plane recently. Checked everything I could think of on the engine itself, no issues. However upon opening the fuel tank, the pick up pipe was clogged, really cl...

beachbum

We did nothing in the end, nothing. At all.

Which was good as it meant more time on the B25 but not so good as it is tough to motivate 5 crew when there is not much going on...

Yannis,

Been a bit of an odd year for the meltemi from what I've heard - i.e. much less than normal?

Fantastic!

Ive taken a washing machine apart to get it down a flight of stairs on the yacht I used to work on (then put it all back together at the bottom), never again

Really looks like it's starting to come together, ktm, nice work

Looks good!

You're giving me loads of motivation for mine in the Autumn.

Oh and is that a sort of dry stone BBQ grill you've got in the garden too?!

Been watching some more of the Aussie Bertram and episode had the guys running the B25 and doing some testing on the water, it looked like it was running pretty good. episode 5 - shows some of the fun from my past, trim pumps not working well, pulling outdrives, pulling motors. Yeah I'm glad I won'...

This might be of interest - a series of videos of 2 Tasmanian guys doing up a 1980 B25

There are 6-7 videos, quite entertaining if nothing else!

Got 2 of these on the Pershing 108 I work aboard. They are fantastic bits of kit, don't require much maintenance and of course there's nothing in the water to worry about (apart from the cooling system). I can certainly imagine that on a 35fter with 1 installed, almost all roll would disappear. Howe...

Another shout out for propspeed. It's expensive but it works. I'll try to dig out a photo of a Sunseeker 92 on shafts that we put propspeed on, came out a year later very clean. Repeated yearly for 5 years. We also tried it on Arnesons under the advice of propspeed themselves and it lasted about a m...

Snipe - what paint did you use? Awlgrip or something? It looks flawless. Sprayed presumably?

I've got the same material as ttownthomas, which is to be removed at some point, this has inspired me

Snipe - that is a work of art

beachbum

Does anyone have any info on the original toilet? I assume trying to get anything for it is no longer possible. I disassembled it the other day and found a few parts that are beyond salvage. I tried using the flush only for a load of very reddy brown water to appear - luckily this was only rust infu...

Wavelength and wave height the same, not nice at all

Well let's just say that my 1968 B25 looks like it was built in 1968, every picture of a 31 / 28 / 25 on this site shows really top condition boats. That stern photo of Cam's boat looks like something that's just rolled out of a factory! (On the plus side, I got my mini gas stove working today so I ...

beachbum

Very nice indeed - yeah I guess in that position the tabs will have much more influence on the bow height than positioned further out (where mine are).

You guys in the US keep your boats in such unbelievably good condition, at least that's how it looks from the photos!

Thanks a lot! This site is awesome

Thanks mike & ktm

177 gallons (presume US gallons..) = 670 litres, which seems bloody massive for a 25fter to me!

I guess when there were 2 petrol engines pushing her along, that 670 litres went pretty quick

beachbum

Couple of extra questions: Anyone know the fuel tank capacity? Single tank version. It certainly looks original. I was told the fuel gauge was working when I purchased the boat. I stuck 30 litres in before doing a quick seatrial and the needle did move a tiny bit. However upon opening the tank to ch...

Looks amazing, that.

Nice work and your boat looks great. Thanks John. My paint guy didn't manage to repair the chips and scratches in the hull, which was mildly annoying as he'd promised me he'd do it, but the boat is starting to come together slowly. The problem with working on a superyacht as the day job, is that yo...
