Detroit 6-71 sea-trial checks engine
Owners suggest checking cold starts, smoke clearing, oil pressure (about 50-60 psi warm at cruise), gear oil pressure (about 300 psi) and steady 175-178F temps at near-WOT; occasional higher-rpm running helps keep airboxes clean.samsmarine.com · samsmarine.com

Engines & parts
Detroit Diesel 6-71 (inline, N / T / TI) parts: good
Factory standard engine — you entered “Detroit Diesel 6-71N”
Two-stroke 71-series engine with a huge commercial, bus and marine population; basic engine parts and complete overhaul kits (liners, pistons, injectors, blowers, bearings, gaskets) are cheap and widely available from Diesel Pro Power, Highway and Heavy Parts and others. Some marine-specific parts (coolers, manifolds) are harder to find. Designed to be rebuilt in-frame repeatedly; naturally aspirated engines with good care have been reported past 15,000 hours, turbo versions more like 3,000–5,000.

Oil leaks engine
Owners describe 71-series Detroits as habitual oil leakers; chasing leaks with the right gaskets and sealants is a routine topic even on freshly rebuilt engines.trawlerforum.com · cruisersforum.com
-
Noise and smoke exhaust
Injector and exhaust noise is loud unless mufflers are well designed, and some smoke is typical of the two-stroke design.trawlerforum.com
