Engines & parts
Crusader 350 / 454 inboard gas V8 parts: good
Factory standard engine — you entered “Crusader 454 (7.4L gas V8)”
GM-based inboard engines; Crusader (now part of Pleasurecraft Marine Engine Co.) still publishes illustrated parts manuals and sells through distributors. Go2marine stocks Crusader manifolds, risers, raw water pumps and ignition parts; Osco and Barr make aftermarket manifolds, and new GM/Crusader base engines are sold by rebuilders.
Parts sources: Crusader Engines, Go2marine (Crusader parts), 1-800-RUNS-NEW (GM & Crusader base engines)
Common problems (1)
-
Clogged or failing manifolds/risers exhaust
Owners find individual risers running much hotter than the others (a sign of internal blockage) and debate replacing vs. flushing; Osco manifolds are often preferred as closest to OEM.marineengine.com · marineengine.com

Caterpillar 3208 (NA / T / TA) parts: good
Factory optional engine — you entered “Caterpillar 3208TA”
V8 introduced in the 1970s and discontinued in the late 1990s (Big Bear Engine gives 1999). Naturally aspirated versions run about 210 hp; turbo and turbo-aftercooled versions go up to 435 hp. Cat dealers still supply many genuine parts by serial number, and aftermarket in-frame/overhaul kits (pistons, rings, liners, bearings) are sold by Diesel Pro Power, Highway and Heavy Parts and others; complete remanufactured long blocks are also sold. The block is unsleeved from the factory but can be bored and sleeved during a rebuild.
Parts sources: Diesel Pro Power, Highway and Heavy Parts (Cat 3208), Big Bear Engine Company (3208 long blocks)
Common problems (3)
-
Aftercooler failure flooding the engine (TA models) cooling
The seawater-cooled aftercooler on turbo-aftercooled 3208s has aluminum parts that corrode; a failure can let seawater into the cylinders. Owners pull, clean, grease and pressure-test aftercoolers every 2–3 years and some replace them on a fixed schedule.trawlerforum.com · forums.ybw.com
-
Short life at high ratings / overloading engine
The higher-rated 3208TA engines last longer when run well below full power and propped so they can reach rated rpm; overheating or running at full load continuously shortens life.trawlerforum.com · trawlerforum.com
-
Overheating at high throttle cooling
Common causes owners check are clogged heat exchangers, thermostats, fouled keel coolers or restricted raw water flow, and faulty temperature senders.justanswer.com · facebook.com

Detroit Diesel 6-71 (inline, N / T / TI) parts: good
Factory optional engine — you entered “Detroit Diesel 6-71”
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.
Parts sources: Diesel Pro Power (Detroit Diesel parts), Highway and Heavy Parts (Series 71)
Common problems (2)
-
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
