I visited the factory a couple of times when I lived in the St. Augustine area, and always liked a couple of their lines, though I had heard of some quality issues. What was your experience with the quality of your Tournament 320?- Hide quoted text - - Show quoted text - It was a good boat. I had the twin 300 Yanmars and at 1000 hrs had to have the water jackets cleaned for restrictions. I paid for that. They, Marine Pro, said I needed to run it harder to keep em clean. I had an issue with bottom bubbles after 2 years and Luhrs took care of the total cost. I had a ZF tranny blow after 20 months,30 miles off Canaveral, tranny had a warranty 1 year, and Luhrs or ZF repaired it on their dime also. So excellent customer service and a nice boat for fishing or cruising. We took it to the Abacos every summer for 5 years and never had a problem. Resale value was pretty good. |

Yeah but those were the guys wouldn't't weigh pistons on a triple beam because it wasn't accurate enough ;-) We do have to credit the Germans and Japanese for making us change our engine factories. We were still building the stuff that allowed us to blow up all their factories. They got a clean start and kicked our ass. My Merc is a Yamaha powerhead. American foot. Best of both worlds in my opinion. Those that keep talking as if 4-strokes are somehow "new technology" simply because they are mounted on the transom of a boat are pretty ignorant. If someone said that 4-strokes have come a long way in the past 100 years, they might be on to something. Most of the developments are not specific to 4-strokes. Materials, manufacturing techniques, fuel delivery... The biggest single advancement in 50 years for the 4 stroke was the overhead cam. That eliminated a lot of valve train hardware. The real enhancement was the computer control but that has creeped into 2 stroke design too. EFI is where most of the efficiency and clean burning came from. They had pretty much squeezed all the juice out of the carburetor by the end of WWII. Fuel injection was dabbled with for a couple decades after the war but the systems were pretty clunky until someone put a closed loop, computer controlled system in there. Combine that with computer controlled ignition systems and we really have a well performing engine. Alas, the ability to fix it on the water (or side of the road) is compromised. Compromised? Hehehe. Yeah. That's the ticket. Compromised. Pretty much eliminated but for the obvious...no spark, loose wire, stuck starter, something like that. No computer hookup, no special tools, no go. I don't disagree with your "well-performing engine" comment, but in the good old days in the 1950s, I had plenty of "well-performing" two stroke engines that started every time, ran just about all day at WOT, and were easy to repair without the use of exotic tools or instruments. |

Materials, manufacturing techniques, fuel delivery... The biggest single advancement in 50 years for the 4 stroke was the overhead cam. That eliminated a lot of valve train hardware. That was a little more than 50 years ago. They were making engines with dual overhead cams more like 100 years ago. The rest of the stuff you list below is not specific to 4-strokes.
