Engine Room Systems:
FUEL FILTRATION SYSTEM: Racor Fuel Filter/Water Separator 10 Micron filter assembly: no water present.
THROTTLE & SHIFTER CONTROLS: Morse cable shifters worked properly at Main cabin.
SEAWATER PUMP: pressure seems to be fine, not leaking at seal weep hole.
TUBE-TYPE HEAT EXCHANGER: checked inlet and outlet flow temperature, within parameters
ENGINE OIL COOLER: checked inlet and outlet temperatures, all within parameters
SEAWATER PUMP OUTLET PRESSURE: adequate pressure
COOLANT LEVEL SENSOR: working properly no leaks observed.
ENGINE MOUNTS AND BED: Main engine beds are heavy longitudinal stringers inboard and outboard. All 8 Engine Mounts show wear and need to be replaced.

LUBE OIL PRESSURE: (WOT) 2600RPM engine 100% load, PORT 58 PSI. STARBOARD 85 PSI.
COOLING SYSTEM TYPE: Freshwater reservoir type cooling with Seawater cooled wet exhaust, Operated satisfactory.
COOLANT LEVEL: Normal levels observed. used heat sensing gun on all cooling system surfaces. operated normal.
HOSES AND CLAMPS: in good condition look to have been replaced recently. Exhaust system hose clamps need to be replaced with Marine SS Compression hose clamps
BELTS AND PULLEYS: Pulleys condition appeared serviceable.
SEACOCKS AND STRAINERS: Seawater seacocks were ball valve type. Needs service looks like saltwater draining down on them from wet exhaust system

EXHAUST SYSTEM: Seawater cooled with risers and flexible coupling sections double clamped where sighted.
ENGINE ALARMS: Test of low oil pressure alarm, and coolant overheat warning audible at helm station. Operated satisfactory.
ENGINE SHUT DOWN: electronic style shut off solenoid switches operated satisfactory
BELLOWS & BEARINGS: Rubber bellows appeared flexible and without leaks. Bearings seem serviceable.
ENGINE ALIGNMENT: Appeared Smooth & without vibration.
RUDDERS: Packing gland style, not leaking excessively appeared serviceable. no vibration.
DRIPLESS SHAFT SEALS: no water detected do not seem to be leaking while underway
TURBOCHARGERS: Shows movement in turbine wheel shaft bearings, currently does not seem to be leaking oil, need to be rebuilt/replaced on both. sounded like they spooled up around 1400 RPM and operated satisfactory
VOLVO PENTA TRANSMISSION & OUTDRIVE: performed adequately while shifting no excessive noise or vibration while under way.
——————————————————————————————-
SEATRIAL REPORT:
1. The engine started without excessive cranking.
2. The engine exhaust appeared normal. very minimal smoke for an engine of this age.
3. The cooling water exhaust appeared adequate and normal.
4. The engine instruments, seem to have a short or loose connection. recommend a marine electrician investigate, otherwise all operate within normal operating limits at idle, cruising speed and at wide open throttle.
5. The steering system operated normally. very responsive.
6. The throttle & shifter: operated normally. no adjustment needed
7. The transmission, went in & out of gear smooth with no excessive noise
8. The backdown test was satisfactory.

📊 Volvo Penta TAMD 63P-A RPM Chart (Approximate)
| Engine RPM | Relative Power | Relative Torque | Typical Use / Note |
|---|---|---|---|
| 800 rpm | Very Low | Low | Idle / maneuvering |
| 1200 rpm | ~25% | High torque range | Slow cruise / fuel economy (higher torque vs power) |
| 1500 rpm | ~45% | Peak torque approx | Strong mid-range torque around here (reports of ~1180 Nm peak ~1700) |
| 2000 rpm | ~65% | Good torque | Efficient cruising |
| 2500 rpm | ~85% | Strong | Near cruising power |
| 2800 rpm | ~100% (Rated) | Maximum power | Full-rated output (370 hp / 272 kW) |
Wide-open throttle (WOT) testing confirmed excellent performance: no smoke was observed, the boat accelerated smoothly onto plane, and the engine delivered strong, confident power throughout. Results indicate the system is operating cleanly and reliably. WOT test 2600 RPMs continuous for 2 minutes, is a little lower than the 2800 Rated Engine Speed. Worn turbocharger is probably the main factor, 195-degree water temperature for the entire WOT test
Recommendations and observations:
- Turbochargers have excessive play at shaft bearings, worn. need to be rebuilt/replaced
- Exhaust system hoses and hose clamps have wear, need to be replaced.
- Engine motor mounts are worn, need to be replaced.
