Guys, after investigating a bit I have got some infos in terms of my yse8.
Option 1. $2000. Local mechanic who has been working on yse8 for many years will pull out head and fix the cylinder, piston etc..
Option 2. $4100. Sydney diesel will completely restore the same YSE8 pull out mine and install the new one. They will keep mine and buy of me another yse8 for parts which is collecting dust and rust in my garage.
Option 3. 13-$14000 Beta 14 hp-/ Nanni 14hp/ Yanmar 14hp/ Volvo Penta 13hp each around 10k plus installation 3k.
option 1 keeps boat affordable
option 2 makes boat with completely restored engine
option 3 makes boat safe when sailing offshore but put cost of the boat to 26k. Is Tasman 26 worth 26k, maybe in my dreams only. I would love to have a new 2 cylinders engine but The price is mad! I am sure that option 1 will make my yse8 strong again for many years to come. I am just not sure if would option 2 be better way to go?
Any opinions welcome. If someone thinks that option 3 is a considerable option please let me know why. I must admit that It would feel cool to cruise to Manly and back with my family while 2 cylinders are working nice and easy and Tasman is smiling around the Harbour just like 30 years a go!
Thank you
How long will you keep the boat for. It will never be worth what you paid plus a new engine. However if it is enough for you and your family for years to come it might be worth it.
Bear in mind, to get full value out of the engine upgrade you might need a new prop. You also need to confirm a larger engine will fit.
Does Option 1 require pulling the engine? Who is going to do that and the installation? If only doing the head it wont include cylinders and pistons [rings] etc. There is also the risk that something might be found and the $2k prices increases.
It's a difficult dilemma, and one I have also thought about when looking at boats to buy.

I hope to keep my Tasman forever. Very nice boat to sail and beautiful boat for cruising around. Very stable boat with a lot of head room inside. option 1 will be done without removing the engine and the mechanics name is Ian. He is Based around the Balmain. His company is called Hume something, I can not remember. Even if he founds something else he could restore it back to its old glory.option 2 will be a swap once the engine is fully restored.
option 3 no need new prop my 11x10.5 three blades prop will do the job and it looks like I have enough space to fit 2cylinders engine in.
Really tempted to get Volvo Penta even I know that Beta are the better engines and you get more for your money. I like the fact that Volvo has less revs and more torque and of course 115 amps alternator is a good thing.
I just got a new alternator for my Yanmar yse8 and I think the options 1 and 2 are ways to go. Maybe option 1 is the best option and I will ask Ian to check every thing in engine and make it sexy for the next 10 years. After that will get a new Volvo Penta??
A really immaculate Tasman 26 is worth about 14 grand. So choice 1 would be to buy that boat and sell yours. The second choice would be rebuild the yse8 in the shed your self. The third choice would be to buy a yse12 and fit that, check whether it's a straight swap first though. Probably more 12's about than 8's. Installing a new engine will seriously over capitalize this boat and you maybe better of buying a larger yacht with the proceeds of selling your boat and 14 grand cash. The market has almost returned to pre covid times now!
I went the 14hp Beta way for my 28 foot Santana. I bought it at the Sydney Boat Show as a Show Special, traded in my 10 hp Buhk ($1000 )
On a swing mooring with the aid of a work boat to lift the old engine out and the new one in, I did the installation myself but got a mechanic to do the alignment. Total cost $8000. This was just pre pandemic. The price of the 14hp Beta alone was $6,318.00

But, if you want a condensed version, here are my thoughts;
Option 1 - Recondition your old engine. My preferred option, but you need to be aware that the mechanic will only fix up the cylinder, piston, etc. The mechanic will probably not do anything to the peripherals such as the water pump, fuel pump, water and fuel lines, electrics, controls, gear box, exhaust elbow, heat exchanger (if you have one?). Some of these are easy to fix (water and fuel lines), but some could be expensive to replace, depending on availability, especially the exhaust elbow and heat exchanger. One other advantage for this option is that you will certainly learn about Diesel engines.
Option 2 - Replace with reconditioned engine. Might not be much more value than Option 1, apart from the warranty. However, the warranty might not cover, for example, a breakage caused by a busted heat exchanger or exhaust elbow or something that is not directly related to the reconditioned engine.
Option 3 - New engine. High cost. Will sort most things. Difficult to justify to the Admiral/Minister of Finance/Family.
Is this of interest. I am not the seller. If it is still for sale in a few months I could be the buyer then.

Thanks guys.
Did some measurements, the only new engine that fits is volvo penta 13hp. Going with Sydney Diesel mechanics they will take mine engine out get the spare one from my garage and fit in a completely reconditioned yse8 from scratch. Saw the photos. It is in pieces on the working table. Total cost 4K. Shouldn't have any issues to reach a hull speed if in trouble for next 20 years. There is no point spending 13k for a new engine. Keep in touch, will report how reconditioned yse8 is Going once is done.

You must choose option 2.
Good to see you on the job mate

Agree, option 2 is the logical choice. #1 is a limited repair, #2 is definitely better and #3 is beyond economic reality. 
And as a word of caution, stay away from any magic lotions and potions in the oil, good quality oil and filters only.

I would go for the Beta. I had a 43hp Nanni years ago and I thought the marinising was quite poor, particularly the wet exhaust manifold. Beta marinising is better.
Even better would be a custom wet elbow on the standard Kubota manifold and a seperate off the shelf heat exchanger giving more flexibility for use of engine space.

Or one could have a long look at the offerings of John Wichard, WM Marine Diesels, which in my humble opinion are superior to the beta offerings, but still over capitalizing the boat in question.

Great thanks I wasn't aware that WM does all the marinising here in Aust so that's a real bonus. And their tech details look top shelf.

I'm not sure what you define as "magic", but when my Yanmar started to blow dark smoke I pulled out some diesel fuel cleaner that the old owner had left on board.
Within half an hour the boat was delivering about 20% more power than it had done when we bought it and was running better than after the open-chequebook annual service. So I'm now a convert to snake oil and magic potions!

I too use a diesel fuel additive, wouldn't leave home without it.

Are they having a second hand engines? I will give a call tomorrow morning to John to see if he can make my Tasman Tiger again!
