1. Some deck delamination on foredeck.
2. Crazing around mast partners.
3. Bukh 10hp seems to have a reputation for being reluctant to start.
1 isn't unusual in balsa cored decks but its not a job I've ever attempted, if you've ever done this I love to know the reality of this undertaking.
2 doesn't sound good and I'm in the dark with this one.
3 really isnt going to make for relaxed boating I fear, there's a glow plug upgrade possible...anyone tried this?
1 I'm afraid I can't help you with.
2 Star crazing can be sorted by using something life a Dremil (sp?) drill to take the cracks back to the fibreglass and then filling them with a thickened, solvent-free epoxy such as WEST. For extra peace of mind, why not first grind back the gelcoat over an area up to say 50mm beyond the cracks and laminate on some more layers of glass, using either vinylester or epoxy? Fill and fair and paint.
3 When I first bought Fantail, her circa 1982 Bukh single-cylinder engine was a nightmare to start. I'd usually decompress it and it would still take a lot of cranking. The head had been replaced, but it turns out that it hadn't been properly machined before going back on (long story to do with previous owner's excessive frugality), so it had to come off again and I got the job done again properly (at my expense, alas). This work was carried out by an engine maestro, one Bill Whittington of Nelson, NZ. I asked him how I could keep the newly-reformed engine reliable. 'Run it for a quarter of an hour every day that you're on board and change the oil once a year whether it needs it or not. It will probably see you out if you do this.' (The manual says every 300 hours, for this robust little beast). I have religiously followed this advice and it starts without any hesitation, even just recently when Fantail went back in after being out of the water for several months. When this transformation took place, I was living in Nelson, where the water and temperature can both be pretty cold, so I think the treatment should work for your engine, too. These engines do have a bit of a reputation for cylinder head problems, but it's the only thing I know against them. Get a proper engine surveyor to check the head, and then follow old Bill's advice.
