aquanaut 750 now in the online auction. everyone can place a bid until 16 november 202why is this boat being sold?the reason for the sale is a serious engine problem. the installed 40 hp peugeot diesel engine is currently not operational. the head gasket has been irreparably damaged and the engine needs to be replaced. this is an important consideration for you as an interested buyer and should be explicitly included in your assessment and budget. the boat is therefore being offered as a project that requires the installation of another engine.
the seller states that the engine started well before this problem occurred and that the boat manoeuvred comfortably, both forwards and in reverse. this information relates to the period when the engine was still operational. at present, the boat cannot be expected to navigate under its own power. the electric bow thruster may provide additional manoeuvring capability with a suitable technical installation, but its operation and usability must be assessed during the viewing day.
what has recently been done to her?the underwater hull was stripped back in may 2026 and subsequently treated with primer, paint and antifouling. according to the seller, the cost of this work exceeded 7,000 euros. this work forms a relevant part of the maintenance history, but it does not resolve the engine problem. the boat was last taken out of the water for maintenance in 2026.
the electrical installation is described by the seller as being in good condition. the boat is equipped with, among other things, a fuel tank gauge, oil pressure gauge and rev counter. As the engine needs to be replaced, it is advisable to pay attention during the inspection to the connections, wiring, instruments and the technical possibilities for installing a new engine.
what is the layout on board?inside, the aquanaut has a dining area, a cooking appliance and mattresses. the sleeping area provides two fixed berths, with room for two additional berths if the layout is adapted. there is a manual toilet on board. the toilet outlet discharges directly into open water. this is important for your intended use and for how you plan to use the toilet on board.
the water tank has a capacity of approximately 100 litres. warm-air heating is installed. outside, you will find a cockpit tent, guardrails, fenders, lines, a bathing platform and a boarding ladder. the boat is also equipped with an electrically operated bilge pump, a lifebuoy and a manually operated anchor winch with anchor, chain and line.
is this boat suitable for your plans?the aquanaut 750 may be of interest to someone looking for an affordable steel motorboat and willing to invest time, knowledge and budget in replacing the engine. her dimensions make her suitable for smaller waterways and sheltered inland waters. with a new or suitable replacement engine, she could once again be prepared for relaxed day trips or longer weekends.
anyone looking for a boat that is ready for immediate use should bear in mind that additional work is required before she can navigate independently again. the engine is not operational and is therefore the central consideration in this auction. it is also advisable to carefully inspect the condition of the hull, the technical systems, the fuel tank, the propeller shaft and the connections.
where can you view her?the boat is currently located in amsterdam. during the viewing day, you can inspect her up close and assess the equipment on board, the living space and the technical components. As the engine needs to be replaced, it is advisable to make a realistic estimate in advance of the costs for removal, purchase, installation and any modifications to the propulsion system.
