Tank capacities — where the figures come from
-
Fuel varies by year
“extra fuel capacity (300 gallons)” — spec database (1974-1984), hmy.com · “200 (catalog value for the Sport Sedan)” — spec database (1974-1984), hmy.comThis entry covers two versions: the HMY powerboat guide says the Tournament Fisherman had extra fuel (300 gal), while our earlier 200 gal fits the Sport Sedan. A dealer video also shows a Sport Sedan fitted with the Tournament Fisherman's extra-fuel option. No builder figure was found.
-
Water 100 gal
No source was found. 100 gal is generous for a 34-ft sportfisherman, so it's worth confirming on your boat.
-
Water heater unknown
“6 GAL. WATER HEATER” — broker listing (1973), powerboatlistings.com · “Hot Water System ... Pressurized Water ... Water Heater” — broker listing (1980), s3.amazonaws.comOnly listings: a 1973 34' Sport Sedan with a 6 gal heater and a 1980 boat with a water heater of unstated size. No builder document found.
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
The 1979 builder brochure's specification page gives dimensions and construction only, and no equipment or option list was found. Our earlier figure of none is plausible but has no source.
-
Stern thruster not fitted
Nothing found either way.
-
Steering unknown
No source names the 34 Sport Sedan's steering. Uniflite's specification brochures from about 1981 show cable steering standard on the 28 Mega and hydraulic on the 42, so neither can be assumed for the 34.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Solid fiberglass modified-V (15 deg) with shallow keel. Tournament Fisherman version has the bridge helm aft and 300 gal fuel; Sport Sedan has 200 gal. Sliding salon doors replaced by a hinged door in 1977. Cruise about 20 kt with big-block Crusaders.
Engines fitted
-
Crusader big-block gas V8 (454) — gas, twin
standard
HMY: standard big-block Crusader gas engines give about 20 knots cruise, 28-30 top. Rating not stated; the Crusader 454 of that era was commonly sold as a 350 hp model, but no source ties a specific hp to this boat.Sources: hmy.com
Generator
Listings vary: a 1973 34' Sport Sedan has an Onan 6.5 kW gas (MCCK), a 1977 boat an Onan of unstated size, and a 1980 boat none. Whether it was a factory option is not documented.
Known problems for this model
-
Fire-retardant-resin blisters hull
Uniflites built from about 1975 used a replacement fire-retardant resin associated with extensive blistering; survey the bottom and topsides for blisters and moisture.nautipedia.it
Engines & parts
Crusader 350 / 454 inboard gas V8 parts: good
Factory standard engine — you entered “Crusader big-block gas V8 (454)”
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.

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
