Tank capacities — where the figures come from
-
Fuel 400 gal
“Fuel Capacity: 400 gallons” — search excerpt (1988), greekyachtsales.com · “400 gallons of fuel” — search excerpt (1988), boattrader.comListings agree with our earlier figure; no Carver/Californian literature was found online at a builder or owners' site.
-
Water 190 gal
“Water Capacity: 190 gallons” — search excerpt (1988), greekyachtsales.com
-
Holding 70 gal
“Holding Tank: 70 gallons” — search excerpt (1988), greekyachtsales.comOne listing (a 1988 boat also shown on other broker sites) agrees with our earlier figure.
Tanks are often replaced or added on older boats — check the tank labels or a survey for yours.
Thrusters and steering — where this comes from
-
Bow thruster unknown
No builder document, review or listing found that mentions a bow thruster.
-
Stern thruster not fitted
Nothing was found either way; our earlier figure of none has no source.
-
Steering unknown

Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Flush-deck aft-cabin motor yacht on a solid fiberglass modified-V (15 deg); hardtop and aft-deck enclosure standard; lower helm optional. Good rough-water performer per HMY. The 52 Cockpit MY is the same boat with a cockpit.

Engines & parts
Caterpillar 3208 (NA / T / TA) parts: good
Factory standard engine — you entered “Caterpillar 3208 (375 hp, turbo)”
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.

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
