Absolutely RV6 I recall some years back having a great deal of difficulty explaining to local launch owners that a compact 6LY Yanmar diesel at 315hp that was significantly smaller and lighter than our ubiquitous 180 Fords was not going to blow up . All about piston speed, the Fords would overheat very quickly at their rated 2400 RPM but the Yanmar could run all day at 3000 RPM, then the Japanese showed me pictures of the same block and pistons running at 600hp! In fact that same block (now electronically injected) is still in production 35 years later. Woops sorry Rich drifting here......
