Tank capacities — where the figures come from
-
Fuel 600 gal
“Fuel Tank: 500 Gallons (1892.71 Liters)” — broker listing, curtisstokes.net · “Fuel Tank Capacity (gal): 520 gallons” — search excerpt, marinesource.comTwo listings show 500 and 520 gal, both below our earlier 600 from the HMY powerboat guide. Listings alone can't change it, but 600 looks doubtful, so it's worth confirming on your boat. A third listing's 120 gal is implausible and isn't used.
-
Water 200 gal
“Fresh Water: 210 Gallons (794.94 Liters)” — broker listing, curtisstokes.net · “Water Tank Capacity (gal): 200 gallons” — search excerpt, marinesource.com
-
Holding 50 gal
“Holding Tank: 50 Gallons (189.27 Liters)” — broker listing, curtisstokes.netOne listing agrees.
-
Water heater AC + engine
“20 Gallon Water Heater Both 110 And Heat Exchanger” — search excerpt (1986), boatsnetlocator.com · “Twelve (12) U.S. gallon capacity water heater” — broker listing (1986), boats-from-usa.comListings only, and they disagree (20 gal with 110 V + heat exchanger vs 12 gal); either may be a replacement.
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
-
Steering unknown
No builder, review or owners' source on the steering was found, and one 1986 listing doesn't describe it.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Sources disagree on engines, hp of larger Lehman option, water heater size — left blank rather than guessed.
Sundeck motor yacht with two staterooms, galley and dinette down, and covered aft deck; also marketed as CHB or Ponderosa 42. Twin 135 hp Lehmans, a larger Lehman option (225 or 255 hp, see disputed) or twin 225 hp Perkins cruise 10-14 knots.

Engines & parts
Ford Lehman 135 / SP135 (2725E) parts: good
Factory standard engine — you entered “Ford Lehman 135 / SP135”
Based on the later Ford 'Dover' 2725E 6.2 L naturally aspirated six (Ford built the Dover series 1982–1994, then Otosan/Dovertech to 2005). Parts are sold by the same Lehman specialists as the 120; American Diesel lists spare-parts sheets and Go2marine stocks cooling parts, heat exchangers and elbows for the 135. Do not assume 120 (2715E) and 135 (2725E) internals interchange.
