DI....
Are you saying that this particular boat has been a problem boat? From what I've found on this site there has been more problems with the 4 stroke engine on the sportster and the one I'm looking at has the 2 stroke 130hp. Now you've made me second guess whether I'm making a mistake in purchasing this boat. Has this boat problems been you're personal expirience? Thanks
The problems you see in the 4-stroke motors are due to a new type application, with bugs being worked out. The 4-TEC engine has only been around for a few years, starting in 2001 or 2, a year or two on, the SC version, then the SCIC by 04 or 05. The 4-TEC engine is set up in a progressive industry that has seen it's simple engines go from standard, sealed integral ignition to these sophisticated sensor input and computer controlled monsters. That's the only way you can turn out 255 ponies on such a small, 3 cylinder engine.
What I think timmyboy is pointing out is the DI (direct injected) model has a history of problems with the compressor that drives the high pressure fuel injection system along with controlling the RAVE valve system. It seems, for those who have this model engine and have had no problems with it, are completely excited with it. It's a great system, when it works well. But, if you have a small problem, the shop will charge you a lot of money in trying to determine what is wrong with it, replacing regulators and pumps till they find out which one was actually causing the problem, at your expense. Now, the RFI (rotax fuel injection) type injection system that is also used, works with less component parts and works on the low pressure side of the cylinders.
I think this is what he's pointing to. If you do not know the history of this engine, then I'd throw a couple red flags at it. Give the engine a look over and see if you can see any obvious signs it's being worked on around the compressor area.:cheers:
