Accommodations
Medium
Morgan Out Island 36 boats used a separate interior liner pan that was bonded into the hull. The bond between this liner and the hull shell can fail over time, causing squeaking, movement, and loss of structural contribution. Check for any separation or flexing of the liner in the bilge and settee areas.
Electrical
High
Original wiring from the mid-1970s Morgan production is typically undersized by modern standards and the insulation is often brittle and cracked after 50 years. The original DC panel and wiring runs should be treated as suspect; fire risk from deteriorated wiring is a real concern on unrestored examples.
Engine
Medium
Early Out Island 36 models were commonly fitted with the Universal Atomic 4 gasoline engine. Many of these engines are now well past their service life and suffer from worn cylinders, failed water pumps, and deteriorated fuel systems. Verify engine type and consider that a diesel repower may have been done — if so, inspect the engine mounts and shaft alignment carefully as repowers were sometimes done without proper engineering.
Hull/Deck
High
The deck-to-hull joint on Morgan Out Island models of this era uses a toerail-clamped external flange. This joint is prone to weeping leaks and, over decades, can develop stress cracking and separation. Inspect carefully along the entire hull-deck join for sealant failure and water intrusion into the balsa-cored deck sections nearby.
High
Morgan used balsa core extensively in the deck of the Out Island 36. Deck hardware installations and chainplate areas are common entry points for water, leading to saturated and rotted balsa core. Tap the entire deck surface to locate soft spots, particularly around stanchion bases, cleats, and the mast partner.
High
The chainplate knees and their backing structures were glassed into the interior liner in this era of Morgan construction. Access for inspection is limited, and the chainplate-to-deck interface is a known leak point that over time causes delamination of the surrounding deck laminate and liner.
Medium
The cockpit of the Out Island 36 drains through small-diameter through-hulls low in the transom. The original bronze fittings are now 50 years old and should be inspected for dezincification and integrity; the drain hoses connecting them are likely original and brittle.
Keel
High
The long keel on the Out Island 36 is an encapsulated iron keel integral to the fiberglass hull. The iron can corrode internally and cause the surrounding fiberglass to crack and bulge along the keel centerline. Inspect the keel-hull junction and the bottom of the keel closely for longitudinal cracking or rust staining weeping through the laminate.
Rigging
Medium
The aluminum mast step and partners on the Out Island 36 are prone to galvanic corrosion where the mast sits in the aluminum step, especially if moisture has been present for years. Inspect the mast base and the step casting for pitting and structural degradation before relying on the existing spar.
