Tank capacities — where the figures come from
-
Fuel 192 gal
“Fuel Capacity: Roughly 192 gallons” — search excerpt (1986), yachts-bysteve.comOne listing agrees; no builder document found.
-
Water 92 gal
“Water Capacity: Approximately 92 gallons” — search excerpt (1986), yachts-bysteve.comOne listing agrees.
-
Holding 40 gal
“40 gallon holding tank” — search excerpt (1986), boats-from-usa.comOne listing agrees.
-
Water heater AC
“The fully pressurized 111 gallon hot / cold water system ... Hot water is provided by an 11 gallon water heater.” — search excerpt (1986), boats-from-usa.com · “6gal hot water heater” — broker listing (1990), seattleyachts.com · “my '88 Carver Mariner 3297 hot water heater ... It's an electric water heater” — search excerpt (1988), yachtforums.comOnly broker listings give a size, and they disagree: a 1986 listing, in wording that looks like Carver brochure copy, says 11 gal and a 1990 listing says 6 gal. The heater sits under the cockpit sole over the engines. No builder document was found to settle it.
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
“Bought a 94 Carver Mariner 330 last spring ... Thinking about installing a bow thruster this spring.” — search excerpt (1994), carveryachtowners.comOne 1994 Mariner 330 owner was planning to add a bow thruster (so that boat had none); no builder list found.
-
Stern thruster not fitted
Our earlier figure of none has no source, and nothing was found either way.
-
Steering unknown
“The steering should be hynautic steering. The pump is at the steering wheel and on port aft wall there should be a stain” — search excerpt (1987), carveryachtowners.comA single owners'-forum reply about a 1987 Mariner 3297 describes a pressurized Hynautic system. No builder document was found.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Sources disagree on water heater size — left blank rather than guessed.
Called 330 Mariner 1993-96; a downsized 3697 Mariner with a full-beam single-level salon and a bridge reached by ladders from the cockpit. Very flat 6-deg deadrise (a forum post says 4 deg) gives a harsh ride in a chop. Over 650 sold per HMY. Build count (approximate, not stored): HMY: over 650 sold.
Engines fitted
-
Crusader 270 (5.7L GM 350 V8) with V-drive — 270 hp, gas, twin
standard
Cruise 14-16 knots, low-to-mid 20s top. An owner of a 1987 boat confirms twin Crusader 270s on 5.7L GM blocks.Sources: hmy.com · boatered.com
Generator
An Onan 6.5 kW appears on one 1986 listing and an Onan of unstated size on another 1986 listing; no Carver option list or review was found.
Known problems for this model
-
V-drive failures and access running gear
Engines sit under the cockpit driving Walter V-drives or Borg-Warner gears with bolted-on V-units; failures come from running low on oil, heat, worn bearings or failed oil coolers, and reaching the V-drive may require pulling the engine or cockpit sole. Watch the V-drive low-oil warning light.boatered.com · yachtforums.com
-
Aluminum mufflers and risers exhaust
Original aluminum mufflers often need replacing (fiberglass preferred), and risers should be renewed on a schedule of roughly ten years or less.yachtforums.com
-
Engine room corrosion in salt water engine
Buyers report corroded, poorly kept engine spaces under the cockpit on salt-water boats.yachtforums.com
Engines & parts
Crusader 350 / 454 inboard gas V8 parts: good
Factory standard engine — you entered “Crusader 270 (5.7L GM 350 V8) with V-drive”
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
