Marine Engine Speed Equaliser Kit | Twin-Engine RPM Matching Meter | Jaycar KC5488

Twin-engine boat, two tachos, and you're still getting that low-end thrum because one motor's running 200 RPM ahead of the other. The tacho itself has up to 5% error, so eyeballing it never works. This kit reads the tacho signal from both motors, compares them in real time, and puts a centred needle on a panel meter. Dead centre means both engines are matched. Off-centre tells you which one's fast and by how much — you nudge the throttle and you're done. No more noise, no more vibration, no more wasted fuel from desynced props. It's a short-form kit: PCB and specified components for 12VDC. You'll need to supply a moving coil panel meter (Cat. QP-5010) for the display

• Shows which engine is running faster and by how much — no guesswork with 5% tacho error
• Reduces noise, vibration, and fuel waste in twin-engine marine setups
• 12VDC operation with PCB and specified electronic components included
• Requires a moving coil panel meter (Cat. QP-5010) sold separately
• Short-form kit — no enclosure or meter supplied
