How easy to service twin mercruisers?

This may seem an odd question, but I have been thinking that I would like to import a 280 SS to Australia, and I am just not sure whether to look for a single or twin engine set up. I am restricted by weight in that I cannot import anything above 4.5t total weight including trailer (and I am looking for a boat with a good trailer). So, I am looking for no later model, I think, than 2004 (I think the weight goes up after that). I am also a bit restricted by price since the exchange rate is not good at the moment. Also, by my calculation I cannot import a boat with an arch, since it is too high for my present shed and I would have to build another shed.

But the real question is single or twin engine? Twin looks like it would be better for manoeuvrability and reliability, but single looks to me like it would be easier to tow (500kg less) and much easier to service the engine. How does one change spark plugs, for example, on the two facing banks of the V8s in a twin engine set up? Looks like it would be difficult. And even getting to the outside banks does not look all that easy. The two engines seem (from pictures at least - I cannot see a 280 SS in real life here - none advertised for sale) to fill pretty well most of the available space. So how do you do it?

I would probably normally use a boat shop to do the maintenance, but even so, there may be times when I would want to do some of my own.

I like my 1997 271 Fastech with single 454 Magnum (though I have been thinking of repowering it and/or replacing the Bravo 1 with a Bravo 3 for better hole shot), but the 280SS seems to have a lot better layout for what we use a boat for. I like the steps up to the front deck, anchor locker, double helm seat, enclosed head, larger double bed, fridge shower. So, would really like to try to get a 280 SS to Australia, but perhaps the biggest question I have is whether I should import a twin or a single engine boat.

I have also had no success so far emailing sellers, even if they are dealers. They don't seem to reply. I guess I might have to try ringing them directly.

I have a 2006 280 SS with twin 350 magnums 300 horsepower a piece 24 pitch props, bravo 3 drives. I bought a brand new trailer for it. I've had the boat one full wisconsin season and part of The Fall season the year before. Love the boat my first boat with twins. access is difficult but it is possible I've done the water pumps, rebuilt them already spark plug shouldn t be too difficult. I'm a mechanic by trade so things are a little bit more easier for me to do the work then her say somebody who doesn't have the skill-set. there's not a lot of room between the motors like if you have to get at the starter on the portside. I think you might have to pull the motor for it. it's definitely tight spaces and you're laying on your belly working on it there's not enough room to go in front of the motors and work unless you're a small individual.
I really like the twin motors over a single motor the boat performs so well and does what you want it to do. gives you much more control at the docks. I don't think you could overload this boat. It is not an underpowered boat. Its a 55 mile an hour boat, great boat.
It's definitely a big step up in responsibility and a learning curve but like I said I really like the boat performance.IMG_20190928_170345969_HDR.jpg

Many thanks for that. I can get a picture of what it would be like and the advantages and disadvantages. Sounds the twin engines make it a much more enjoyable boat, but yes maintenance is somewhat more difficult. Thanks again.
