Transom replacement suggestions - what to do in terms of bungs, ice box, other bits

[ozscott]

Hi all,

I am replacing the transom from inside out on the Vagabond while the motor is off. I am getting an experienced fella to do it. What extras/special things should I be looking at. Its got a full width transom well. I am thinking that on the side not used to access the boat, in and out, I should fill part of the well with an ice box with drain back into the rest of the well. For the bungs I have heard several ideas, but whats the go - re-use my brass ones or get with the times and use some jumbo ones covered in marine silicon. I have heard the idea on here before of drilling oversize, then filling with glass and then drilling smaller for the bung, so that any leaks do not go into the wood, but I wonder whether this reduces strength because the glass is a plug and not keyed into the wood.

The transom will be built up 5 inches for the longer shaft motor that is going on.

In terms of the transom, what wood is recommended - or just heaps of solid glass instead?

Anything else? Its my shot at getting it spot on.

Cheers

Have you had a look at the set up on the later model Vags? As you probably know the later ones like mine have an insulated box with drain to the well on one side and a plumbed livebait box also with drain to the well on the other side. From memory they drain out the bottom and then a hose discharges into the well wall.

Thanks Chimo - will have a look mate!

Hi Ozscott

Just a thought, why don't you contact the Haines people and see if you can purchase the complete transom bin module that you could then build into yours. Also talk to Jabba as he had Haines redo his Vermont after others had made a mess of repairs. Could really be worth going to the horses mouth and even getting them to do the job. If you going to pay someone I always feel you may as well pay the people who know what they are doing rather than paying someone to gain experience at your expense!. That just me tho!

Cheers

Hi OZ The big move finally, no more 115 two stroke. Could hardly believe my eyes.:o What will you be replacing it with?

With regard the transom material I don't think it matters much what ply you use so long as its a water proof glue and its not full of knots. Hardwood ply will rot just as quickly as pine or luan.

You can go with a synthetic material like 10mm core mat that will never rot. Ply will last a long time if kept dry.

Hate to say it JJ but he still has not seen the light and remains part of the Yami brigade,There is hope for him yet but time is running out.;D;)

[ozscott]

JJ. See this thread matey. Cheers

OK - stock + 5 inches for the transom and otherwise pretty standard. What is the consensus on the top cap? I take it as long as the top is glasses so the wood is encapsulated and as long as you smash the screws with sika flex and sika all under the cap, water is not going into the wood via the screws. The cap is really needed isnt it for the motor brackets?

for the transom capping just oversize the holes for the screws or betterstill fibreglass the top edge of the transom where the capping would go to totallyseal it up...

core mat is used generally used for stiffening hatch lids where extra rigidityis required

for ply use structural c-d grade ply

if you want to use a synthetic use something like klegecell or divincell

The boys are doing a great job on the boat. Visited her this arvo. See attached pick. Will be stronger than original. Stringers were solid. So Q-Cells going on and then gel coat and fared in. Transom drain hole still to go in. This boats had about 13-15mm solid glass right in - as it is they went about 4 inches over the solid glass area, so the pic shows how far in the glass went.

Should be ready Monday and then motor on and off for a trip!

Hi

Are they going to put the stainless pipe inserts with a flowcoat covering in the transom bung holes upstream of the bungs as per the original transom?

Cheers
Chimo

[ozscott]

No mate. It will be glassed and gel coated so good seal against moisture. Cheers

[Jarrah Jack]

Those Seafarers were made to last. Very impressive the amount of glass in the origional transom.

7417374174Here it is. She is solid as a rock. The boys have done a nice job I reckon. They are Moreton Bay Boat Doctors and Detailing Pty Ltd - ask for Mitch for the building/detailing and Ty for the mechanicals.

In the photo I am getting rid of the old deck wash lines and will replace them with a neater setup.

Cheers

7432374324Here are some photos of the finished product...this motor starts within 2-3 second cold and instantly hot. I have only had it on the muffs but she crackles and sounds very sweet. Cant wait to get her out. Whereas before the anti cav plate was half and inch or so below the hull now its a little above, which, provided there is no cavitation should make it pick up a knot or two. It came with a sports se foil. I had one of those new and gave it away because I fitted Bennett tabs...now I will try it on, but take my sockets with me in case it needs to be removed. The motor is immaculate - it looks new. This saltwater series for me will be a keeper. It only has 300 hours on it and I am looking to get (at least) 10 years out of this baby. It has the fresh water flushing attachment at the powerhead which is handy, but I will use the muffs most of the time.

Cheers

I'd be very interested in how the motor lift changes the steering Ozscott, particularly ease of turning at speed.

[ozscott]

Fed - I put a Teleflex No-Feed-Back steerting helm and cable in her a few years ago and it has been excellent. Keen to water test her.

Ok - finally got the girl out - took my boys to the Rouse for a 2 day and overnight trip. Beautiful weather got back yesterday late. Stayed in Horseshoe Bay to get out of the NE winds. Drifted the banks for whiting and the boys caught heaps of juvenile snapper on the way home near the Rouse.

The new (99) motor Yammy 115 2 stroke rang like a gem. Started first time at the ramp. Per the last Yammy I am using the semi -synthetic Merc oil. She idles quieter than my 93/93 one and is smoother and quieter through the rev range. The early to mid throttle openings produce a smoother and more linear engine response - they have certainly improved them over the years. The engine has a little more grunt too which is nice. Top speed is a little faster. We were heavily loaded for the 2 days away and 155 litres of fuel, but she still hit 63kph in half metre chop. She cruised happily and quite quietly at 45kph and 4500 rpm and 28-30 litres per hour.. 5500 shows top speed and 48 litres per hour.

Against my better judgment I tried the SE Sport foil - tried it for 10 mins out of Raby and then straight back to the boat club to land on the beach and remove it...much better without.

The extra height on the transom was nice when the bay chopped up a little the next day. Feels good doing 50kph above the sharp chop across the paddock with a rock solid set up - knowing it for sure and not guessing at the stringers and transom.

The only thing that I need to correct is the tranducer placement. The boys who did the transom put it a little high and it is not reading above about 20kph.

All in all a great few days away.

75364Hi Oz

Good result. In post 14 I assume the tabs are not in the home (up) position.?

Also I can see why the Sport Foil came off. Their down angle at the rear end is way too severe.
When I compare it to my foils, Which I'm happy with, they are flat hence no pretense about being a trim tab.

[ozscott]

Chimo - post 14 up position, post 15 shows down position.

Cheers mate

Did they replace your tramson from the out side by the look in your pic im just about to start 19'boat some say u have to do it from inside the boat
Would like some input thanks

[ozscott]

Marcus - two schools of thought. The late Holloway who used to feature in the Jeff Webster guides (who did a floor for my Haines years ago) advocated outside in. It depends on the boat and how much coin you have too. In my case the inside skin of the transom was twice the thickness at over a cm than the outside, so the decision was clear in terms of strength. I also wanted the transom raised which sealed he deal for me.

Cheers
