+1 to that. New diesel going to set you back $10 to 14k -more than the boat is worth. Any provision for outboard well?

Now, you mentioned;
It never has enough grunt, overheats a lot and keeps giving me problems.

Following Ramona's advice will give you and indication of whether it is an easy fix (due to lack of maintenance) or needs a rebuild due to wear and tear,
Not enough grunt? Is it burning or using oil? (That would indicate internal wear)
>>> not to my knowledge.
Overheating doesn't mean that you need a new engine. It means that you need to find the reason for the overheating and fix it
.>>> done 2 x acid flushes and it improved. Maybe I should do it more often.
What are the other problems?
Is it starting easily? (Hard starting is a real problem)
>>> Used to start easy but I wrapped my kayak rope around the propeller about 3 months ago and it's stuffed the motor since then.
Does it stall?
>>>Doesn't start now.
Making strange noises?
>>> No
How does the gear box seem? Remember that if you buy a new engine you will be up for a gearbox too.

If you are turned off by a rebuild,here are some reasons to rebuild the Sole. (yourself)
1, if you do it you will know the engine inside out.
>>> agreed
2, The coupling, shaft and propeller are there and are correct
>>>Yes
3. 14 hp is plenty for a 8.5 metre boat. (What do you mean not enough grunt? )
Not enough grunt could also mean a dirty hull or fouled prop.
>>> Hull and prop are ok, it's the overheating that causes issues as I have to turn off the engine after about 30 mins and can't rely on it over a decent period of time.
4. Rebuilding will be MUCH cheaper.
>>>Ok I like that
5. If you rebuild it will give all of us on SB a new project to follow and advise on. (Maybe not a real big plus)
>>> Ok I think I have a new project for you to follow.
6. Working on older simpler machinery is actually fun and satisfying.
>>>Yes I'm starting to see that. I have enjoyed tinkering and learning about the yacht over the last 2-3 years.

My boat is in Drummoyne. I could have a look at your engine with you and maybe give you another view on it. Let me know if you are interested.

Thanks Ramona, have done the acid wash a few times but wonder if it's really getting all the crap out.
What is FTC and what does it do?
Rebuild looking to be far cheaper than new engine so this is what I may have to do.

Cheers

Apologies if I am into egg-sucking territory, but is the prop clean? Even a little growth will dramatically affect performance.
>>>Yep clean it pretty regularly.

Is the prop the right size?
>>>Not sure about this and have wondered if that might be part of the issue. Will measure prop and confirm ASAP.

Does the engine rev out (underpropped), or does it max out with smoke somewhere below maximum revs (overpropped or dirty prop)?
>>>Not sure what this means (sorry). I run it on 1600/2000 RPM for approx 20 mins and it starts to heat up and gets to 100 degress celcius and starts smoking (have a heat gauge). That is when I turn it off.

Does it start easily? If it does it is most likely to be pretty good inside and the problems are on the outside.
>>> Starts pretty easy (normally) although a few months ago I wrapped the kayak rope around it and it smoked more than usual when I ran it for 20 minutes after that (especially on right side near starter). Now it won't turn on and need to get a mechanic or local expert to help.

Whilst they may be a pain to track down, it will be much cheaper and less grief than a rebuild.
>>>Yep I'm starting to realise that might be the best option. What I'm lacking is knowledge on marine diesel engines so just need to get some help on it. I actually really enjoy learning about the boat and the engine (bloody addictive, especially on a Saturday arvo with the footy on, few cold beers and no kids/wife around..haha.

You certainly don't need more than 14hp for your size boat , a bigger engine is not the correct path to go down.
>>> Rodger that and it's good to confirm.

Dunno what your skill level is,(>>>low at this point) but learning everything you can about your engine and drive train is invaluable interms of safety and $$$, and pretty much essential if you're going blue-water.
>>> That is my learning goal for 2019, get it blue water ready and also my skill level

Stories of awful outcomes for people with little older boats like ours, at the hands of diesel mechanics who would much rather work on big new boats, are sadly very common, so learning is your friend. As an example, on the Compass owner's forum at the moment there's a lament by a bloke who was charged $7500 for replacement engine mounts. I did mine for about $600.
>>> Yep I don't want that fate and prefer to learn and do it all myself.

Good luck sorting it out! Lots of clever people on here to help>>> Thanks mate and helpful guidance for me.

+1 for Ramona's comment about shell - I had a small growth inside the nipple on the CW seacock which took weeks to find and drove me nuts. Also remove the CW hoses and either replace, or ensure they are clear.

If you MUST change engines then I would recommend a Beta. They are Kubota based and marinised in the UK. I put a 14 hp
in my 28 footer replacing a very muched stuffed 10 hp Bukh, cost of engine was $7000 with the Bukh traded in. I fitted it
myself but used a local mechanic to align it. Performance is outstanding in comparison, But if you go down this road you have
to be prepared for some mucking around getting it to sit properly on the engine bearers. Alignment is everything. I have absolutely
no regrets purchasing the Beta. Think about the advice the forum is giving you before you commit yourself though.

Thanks Wongaga, will do. Pardon my rookie ignorance but what does CW stand for?

Hey Ramona,

Where did you source your Metal Glean from ?
