our project

[piquet95971]

With the drive flange installed on the inboard end of the prop shaft there is not enough length in the compartment for the engine before the front pulley hits the back of the seats in the fwd cockpit.

I have roughly worked out that I need a prop shaft that is 110mm shorter.
I can only assume that the previous engine was possibly direct drive as at a guesstimate the dog box is about 110-125 mm long.

Shaft length is 1398 mm/55 inch probably need 1288mm/50 inch.
I know Rolco have 48inch/1219mm.

I think that I will probably shorten my shaft and get a new key way cut.

The reason that I am having problems with putting this engine in the boat is that it is not the original engine. I have no idea what was originally fitted, how it was fitted, or what went or goes where. It's a bit frustrating but il get it sorted sooner or later.

Steve at Moritz Marine has prop shafts of different lengths with the prop taper and thread end done. He will cut them to whatever length you require and machine the keyway to suit. He does lots of work for members, he did the 2 blade prop and the shaft for Jayme II.

Progress is still happening although I seem to be slow.

Cockpit trims installed. I was looking for brass escutcheon pins for fixing the trim but they proved impossible to find. So I went through the tray of copper nails and found some suitable items. The trim is now held in place with some epoxy and small copper nails.

After the last coat of varnish was allowed to dry I was a bit disappointed with the finish. I have rubbed it back ready to spray another coat.

Tomorrow I will start to varnish the seat frames.
I have found someone to make the seat cushions so will get the vinyl and foam and then drop them off to get them done.

Vinyl cut for the boats name plate is organised as is the rego numbers.
Still haven't worked out how I'm going to get the engine in the boat yet but I'm working on it.

Cheers
Happy new year guys and gals

Should be ready for a debut at Yarrawonga then? Really looking forward to seeing the finished product. Keep up the good work Peter

I'm not confirming anything but that might be the aim. We aim to please although sometimes we are just plain awful shooters!!

Although IF the Project was to make an appearance, then it would be static on the trailer so that the assembled multitudes could see that it does exist and not just in print, as I doubt that the main propulsion system will be up and operating by then.

The detail work continues. I have sanded off the whole deck ready for a final wet and dry before the top coat gets sprayed. This will be done when the crappy weather goes away

Tomorrow I am taking the plunge and putting the engine in the boat. Everything seems to be ready. I have the mounts and think I've worked out which way they go. I am going to use a friends workshop with an electric winch and a swinging gantry which should make the installation a bit easier.

I tried to get the trailer registered, that was a fail. Vicroads seem to change their requirements every time I go in to their office. I even went in to get the paperwork checked before I made the appointment for the registration. What a pain. Now have to get the required info and make another appointment. At present it will be driven with a permit, even the trailer lights all work which is a bit of a shock. The light bar hasn't been used for 3 years.

So here's hoping that the installation is fairly straight forward.

IT FITS!!!!####****

The whole exercise went relatively smoothly. From the time arrival at the workshop until it was sitting in the hole that it was supposed to fit in was less than 30 mins.

To get the engine to hang close to the anticipated angle we had to put an extra couple of shackles on the leg of the sling that was under the dog box.
Of course the next 3 hours were getting the whole thing to sit properly and getting the adjustments somewhere near right.
I had to move the engine a bit further forward that I had initially thought it should be placed to a get clearance for the sump to the ribs and also to get the two flanges to line up
Across the boat it is now spot on for position to the flange. I still have to adjust the front of the engine up a bit as there is about 5 thou difference between the mating surfaces at the top of the drive flange to the bottom.

I have to modify the length of the water pump drive shaft and may have to get a diferent pulley as the engine hatch wont close because of the taper on the waterpump pulley currently fitted.
The propshaft length is only about 25 mm too long. Tomorrow I will go back to the workshop and shorten it. I'm hoping that I can get away without having to get the keyway lengthened.
I went relatively painlessly
It is only sitting in there with a couple of Coachscrews holding it in place but the engine is so heavy that it isnt going anywhere.
We used a strain gauge on the engine and it came it at 290Kg and on the way home Ii called past the local waste tranfer station (Modern version of a tip) and ran it over their weighbridge. The boat, trailer and engine together weigh 860 Kg.

There are still a few things to be added like fuel tank, fuel, oil safety gear and the like so at a guess i think it will come in at about 920 KG

So an eventful and productive day was had.

It has ben sugested that I might think about firing a flexble shaft coupling. Is this a good Idea or should I just go with the solid connection
Opinions sought and appreciated.
