    SOLD - Pair of 380hp Monty Racing V8's, 25" offshore mids w/CLE lowers

    SOLD!

    For sale is a pair of Monty Racing built V8's on Evolution Marine custom 25" offshore midsections with Mercury 4-hole CLE counter rotating lowers. Fresh water use ONLY!

    Motor specifics:
    • Both motors started out as 4.0l blocks, were bored .020" over and had new Wiseco forged pistons installed.
    • Monty Racing performed his MOD I level port work magic with finger ports (see his website for info and costs http://montyracing.com/html/price.html)
    • Both motors run stock air box with mid-bore carbs and large (3-screw) throttle plates. VRO pumps have been removed (premix only).
    • Hand lapped reed cages with Boyesen reeds.
    • Port motor has stock 6700rpm powerpack, but starboard motor has CDI 8500rpm powerpack.
    • Port motor dynoed 381hp/339tq, starboard motor dynoed 383hp/340tq.
    • Evolution Marine lightweight fiberglass lift off cowls with Johnson Offshore 1 decal set. These have a few small spider cracks here and there from age but are in really good shape. Very light for the size.
    • Starboard motor looks to have a water leak from the gasket under the regulator/rectifier. There is slight water evidence on the back of the block.
    • Starboard motor had a crack in the water jacket on the rear of the block which was welded years ago. No leaks now. This is in a non-structural area of the block.


    These motors have roughly 200-225 hours on them. Ran a compression check the morning of July 6, 2016 in Las Vegas at 2100' above sea level, cold, throttles closed. Port battery might not have been fully up, but you can see the spread. UPDATE: I will be re-running the compression numbers where the motors are in FL soon to update withe a fresh battery and near sea level air pressure.

    Results:

    Port: Star:
    1:133# 1:149#
    2:135# 2:143#
    3:132# 3:148#
    4:136# 4:144#
    5:131# 5:148#
    6:130# 6:145#
    7:130# 7:148#
    8:127# 8:143#

    Midsections:
    • Originally built by Evolution Marine
    • 25" with custom grafted offshore snouts
    • Dry stacked, with rear water outlets.
    • Exhaust adapters have been drilled for additional water inlet. These can be easily plugged. Currently, I have a Jabsco water pump in the boat that pumps water to each mid using 3/4" hose to supplement the CLE water pumps, which are lower volume than the original V8 pumps. This has a one-way valve that prevents WP pressure from going out the adapter. This is helpful at idle to keep the motors fully cooled.
    • Starboard motor trim has a leak on the left low speed trim ram seal.
    • The white stuff on the mids is just hard water. Needs a good cleaning with some CLR and will look like new.


    Lowers:
    • 4-hole CLE's with custom adapter plates.
    • Fresh Merc hi-perf gear lube ~5hrs ago (April, 2016).
    • New water pumps, April 2016
    • LH is straight skeg, 1.87 ratio, small shaft.
    • RH is swept skeg, 1.87 ratio, small shaft.
    • Custom shifter linkages use modified Mercury shift shafts (push/pull to rotate).
    • RH case had a crack to the left of the pinion where a broken pinion cracked the case years ago. This was welded, then JB welded inside and out and does NOT leak.


    Motors are currently in Port St Lucie, FL. $10,000 for the pair, plus shipping/crate. $5,000 each, if the left goes first. If you buy the pair, I will include the steering rams, wing plates and tie bar! Would prefer a local pickup. Would entertain Merc 2.5 15" factory offshore midsection on partial trade. Questions?
