I may be way too late to help but here goes The engine is a Peugeot 2112 cc XD90 Indenor engine as used in the Peugeot 504 and most Peugeot parts are directly usable for your engine. American Diesel USA, Lancing Marine
in UK and Greg Lilienthal of Bomac Marine
USA are 3 key resources. New starters are available but for about $400 when last I looked but if you have an old one all internal parts are available, fuel
injection pump....I have one spare but it likely needs a rebuild
, water pump for the engine fresh water is very available, made by GMB and others they may be had from the water pump warehouse and others. the Johnson saltwater pump is likewise available on the internet
. I bought most of my parts from the UK as this engine was used in the Ford Classic. If you get really ambitious India
used this engine a jeep like vehicule and still make it new for use in irrigation pumps and generators. If you need any other Lehman parts I may have a spare but I am slow to respond because my boat is in Honduras!
