That's interesting, when I left my engine/prop guys to their own resources they suggested 18 x 24s which I have over-ruled based on the information here. My guys tell me they have been getting better than factory results for all their other engine/prop installs but none on B31s. But I just can't see...

Guys....guys, settle. We're trying to sort out the props remember!

Mr Minton,

A very different pitch and higher maintenance too

From searching the old board the consensus seems to be for our B31fbc Yanmar 315s 2.03:1 ZF63a that the props should be 4 bladed 20" x 23". Any comments? We expect to be at the lower end of weight estimates, early hull but no generator, air, desal or tower - a day boat with teak cockpit & moderate f...

Thanks for all your help with technical information everybody, we've settled on the Yanmar 315s and they go in the week starting December 4 in an undercover shed. We've got a promise of two day turn around on the shafts allowing us to measure exactly when everything is in situ. We'll open a book on ...

Guys

Are all the B31 shafts the same length - 72 inches?

Thanks

Scot, Just going through the very same thing. We are glassing a f/g pipe through the transom and fitting a flap as well as fitting a riser to the exhaust by the engine. Not so much the momentary back pressure but to avoid any chance of a gutful of water coming back into the engine. Maybe over-cautio...

Could I please have some views on what the minimum propeller tip clearance should be to the hull for a Yanmar 315 installation, ZF63A 2:1 3 bladed on our 63 fbc. I always believed 10% of dia was OK but I'm getting conflicting advice. Also, I've searched the old site for 3 bladed propeller sizes but ...

Dan at High Tide just quoted me $1,198 for a pair of Aq22 x 1.5" shafts.

We got a decent pair of eyes under the port bunk, wet it down and our date is 04...05...1963. Here we call that the 4th of May but where it was written I think that's the 5th of April which ties in with Mikey's advice.

By her next birthday she'll be like new again!

Thanks Capt. that's exactly what we're thinking/hoping & I always wanted some clean combustion air from the bridge.

Nic

Thanks for the correction Capt. Patrick, that would have been weird! The flying shot of Buddy Boy shows a similar hue. The President of the paint committee has the casting vote and it looks like white, Bahama Green boot-top and light green a/foul - and that was before seeing your late vote Phil. Wha...

nic

Thanks guys,

I make that 3 for white (incl. Tom & his proxy for UV), 4.5 for FL Yellow, (.5 fr Scot for close second choice), a very eloquent case for Buff fr Capt. Patrick and one informal vote.

I'll post a picture of the results of the poll in February 07.

Keep up the great work!

Nic

nic

Thanks Capt. Patrick, we're going to investigate some extra air down the pilasters from a f/b vent as well, maybe directed for combustion air, as we are focused on minimising noise.

It's getting very close & and it's looking like the Yanmar 315s!

I think I remember in the 80s the Anniversary Edition came with 3208s.

Have to be tight.

We are going to paint the hull topsides on our 1963 fbc. The superstructure is white/white, the antifouling is green. The choice for the hull is White.....a very pale Buff....or....Fighting Lady Yellow.

You guys decide, we can't.

Thanks

Almost ready to start the repower to diesel on our 1963 fbc. We have hull side air vents a little over half the size/volume of those on 'Buddy Boy" so we are planning to double up - then I noticed that a lot of boats on this site and on Yachtworld have NO hull side vents at all. My experience is eng...

Scot, You've obviously done a lot more than most on this topic, so I hope my suggestion of another alternative is not a red-herring. If ultimate fishability is not the priority then a single fixed surfacing propellor would resolve a lot of performance/weight issues. I have seen and driven simple fix...

nic

Top idea! Suggest name and age of the boat on each stamp rather than the artist, though that could be fun for the big kids. Looks like it's ready to go now. Love to get some.

Does anybody run this all by Raymond Hunt Assoc.? I'm surpised they don't participate in the forum, did they ever?

Nic

I've never seen the teak edging before. Just a thought John, on our FBC the top half of the bulkhead on the port side, and the door was removed making a semi-open sportfish with stand-up head to starboard. Works beautifully.

I think Bruce has got it.

NY Times was running a story online yesterday that listed 83,000 long contracts for oil in August and 22,000 now. It has sent two hedge funds bust so far according to a friend who is very long on oil.

I hear it sold for $35k.

I second that sentiment. I've owned a lot of boats & driven hundreds more. I was in the boating industry for 25 years and I co-owned a 52ft Ray Hunt Custom Sportfish (built 1971) that was really just a big version of the 31 and of all of them she is the only one to come close to the 31, but our 31 i...

Bruce, I see the 250s are referred to as the 260s as well by Steyr on their website, so sounds like the 280 & 300 are the same. The guy here has been told the higher hp version will be available early '07, which isn't far away, our offer on some 330hp Cummins was rejected so we are going to have a c...

nic

Thanks Mikey,

I'll go and have another look.

Nic

Walter,

Our No. 330 looks like it has an 11th month date so it was November 1963, for the 229th if that helps you with your build date.

Nic

nic

Thanks guys, the 229th is getting closer to her repower - made an offer on a pair of Diamond Series 330hp 6BTAs. Will let you know.

Nic

nic

Our hull No. is 330 and it looks like 1963, but the date isn't clear. Does anyone know?

Thanks

Nic

nic

Bruce,

In looking at the Steyrs here they tell me they only have the 250hp and the next one will be 280hp on the same block. They can't tell me when the 280 will be released though, do you know? Do you agree with these being the correct hp?

Thanks

Nic

DavidR, When I was checking out the Cummins remans Tony Athens was very helpful, knowledgeable and professional. Here is his contact if you want - Tony@SBMar.com . They are not available in the 270hp, only at 330hp or higher which from what I've gleaned from the site you would not want to consider a...

John, I had a very good run with Hynautic controls in the 1980s. We used the plastic lines - no problems really. The fluid we used was a water/glycol mix (i.e. anti-freeze) rather than a hydraulic fluid, so if you had a problem it would be hard to run out of fluid. I'd try fixing it if you can and I...

nic

Well yes and no. I'm sure they don't fit, I guess I was just hopeful. I saw a pic of the other engines and they looked like 6V53s to me. I'm pretty sure the 4V53s are two pots per side, so they are much shorter than the 471TAs, also at a dry weight of 1,800lbs they are just too much metal. Thanks fo...

nic

John, Congratulations on your 31 purchase. I am intrigued by the engines and wonder whether you could send a photo of the engines in the engine bay so I can re-assess the chances of fitting a pair of 4-71TAs into a 1963 31. My email address is nd@2088.com.au and I'd appreciate as many low-res shots ...

Guys, we are being reluctantly dragged to the painful decision of spending real money to get real engines, which we know and you know is the right thing to do - it just hurts.

Anyone got any knowledge of Detroit 471-TAs in a 31. The measurements look too big, but I'm not sure and the engines are a plane trip away. The guy selling them tells me they measure Length 1530mm (60ins), width 830mm(32ins), overall height 920mm (36.22) and height above top of mounts 700mm (27.55in...
