Welcome to Quayworks

Overhaul and Rebuilding

£2,599.00 inc. tax
Quayworks offers a full strip and rebuild service for your long service Isuzu. Generally these engines will plod away in your boat for upwards of 10,000 hrs without needing anything more than oil changes.

As with all machines, the time will come for a rebuild; with the right reconditioning these come out as good as new - check these out:

Rebuilt 35hp

Rebuilt 42hp

Our rebuild process is thorough and proven, with our rebuilt engines in daily heavy use in the country's leading hire fleets. 

Prices start from £2599 depending on what is required - contact us for a written quotation. We normally require the engine for 3 weeks, to allow time to get the machining work done, and to allow time for the specialist works such as injector rebuilding. 

Note if the engine has seized on the crankshaft it is probably beyond economic repair as crankshafts are around £1000 on their own. 

All parts used are genuine Isuzu.
