Tank capacities — where the figures come from
  • Fuel 120 gal
    “Fuel capacity 120 gal.” — brochure (1987), wellcraft.com · “Fuel tanks, 2-60 gallon aluminum with crossover” — brochure (1985), wellcraft.com · “Fuel Capacity 120 gallons” — brochure (1985), wellcraft.com
    Wellcraft's own product-information sheets give 120 gal: the 1985 sheet describes two 60-gal aluminum tanks joined by a crossover, and the 1987 sheet also gives 120.
  • Water 28 gal
    “Water capacity 28 gal.” — brochure (1987), wellcraft.com · “Freshwater Capacity 28 gallons” — brochure (1985), wellcraft.com
    The builder's 1985 and 1987 sheets agree on 28 gal.
  • Holding unknown
    The builder's sheets list an electric head as an option in 1985, and an electric head with holding tank as an option in 1987; neither gives a tank size.
  • Water heater 12 gal · AC + engine · factory option
    “Optional Equipment: Hot water heater” — builder (1985), wellcraft.com · “Optional Equipment: Hot water heater 120V, 12 gal.; Hot water heater w/exchanger 12 gal.” — builder (1987), wellcraft.com
    The builder's product-information guides show a hot water heater as an option in 1985 (size not given; shower and pressure water were also options), and in 1987 a 12 gal heater offered as 120 V only or 120 V with engine heat exchanger.

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 not fitted
    “Standard equipment and optional equipment lists (1985) contain no thruster” — builder (1985), wellcraft.com · “Standard equipment and optional equipment lists (1987) contain no thruster” — builder (1987), wellcraft.com
    Wellcraft's 1985 and 1987 product information guides list all standard and optional equipment; no thruster in either.
  • Stern thruster not fitted
    “Standard equipment and optional equipment lists (1985, 1987) contain no thruster” — builder (1985-1987), wellcraft.com
  • Steering unknown
    “OPTIONAL EQUIPMENT: ... Hydraulic steering” — builder (1987), wellcraft.com
    Neither guide names the standard system (1987 lists only a stainless Destroyer steering wheel as standard); hydraulic steering was a factory option in 1987. The standard was presumably mechanical cable steering, but no source says so, and the 1985 option list doesn't mention steering.

Thrusters and steering are often replaced — check the units on your boat before ordering parts.

Called 288 Suncruiser 1981-82. Solid fiberglass modified-V (16 deg); most have straight inboards under the forward cockpit (no mid-cabin). HMY's text mentions a 1995 floorplan update, which conflicts with the 1987 end date and is probably a typo.

Engines fitted

Boats of the same model can differ — check which engines yours actually has before ordering parts.

Generator

factory option

“Optional Equipment: Generator - 4kw gas” — builder (1985), wellcraft.com · “Optional Equipment: Generator-6.5 KW and muffler” — builder (1987), wellcraft.com

Generator was a factory option: 4 kW gas in 1985, 6.5 kW in 1987.

Generators are often replaced or added — check the unit's own plate before ordering parts.

Engines & parts

MerCruiser 5.0 (305) / 5.7 (350) V8 gas parts: good

Factory optional engine — you entered “MerCruiser 350 (5.7L) gas inboard”

GM small-block Chevrolet base engines, so internal parts are everywhere. Marine exhaust manifolds and risers for 1983–2002 small blocks are sold by many aftermarket makers (Sierra, Barr, Osco and others) through Power Boat Supply, Hardin Marine, Basic Power Industries and similar stores; Mercury sells genuine parts through dealers.

Common problems (2)
  • Manifold/riser failure and water in cylinders exhaust
    Cast-iron manifolds and risers rust internally or their gaskets fail, letting water back into the cylinders; small amounts cause hard starting and rough running, large amounts hydrolock and wreck the engine. Service roughly every 7 years in fresh water and about 5 in salt.
    powerandmotoryacht.com · forums.iboats.com · justanswer.com
  • Overheating from scaled manifolds cooling
    Rust and scale inside the manifolds restrict cooling flow and cause overheating under load.
