[QUOTE="Pappy, post: 362769, member: 3278"] Those were amazing engines! Bulletproof!! I remember we ran a pair of them WOT on a test boat for 500 hours without a hard part failure! Took them apart and re-assembled them again and put both of them back into endurance testing. Those were the only engines the test drivers never backed off the throttles when they were jumping surf with. They just let 'em eat! The port schedule in those engines was so mild it was almost like having a built in RPM limiter. [/QUOTE]
