I've run my DF50 from new for around 540 hours (in freshwater). Twice a year-ish I do a long run into remote areas of the Amazon with guests (longest one was 1500km), and I need to try to take along as many spares as practical to cover any eventuality. I thought I was doing fine until recently, when my motor just stopped for no apparent reason, leaving me a seven hour paddle to get somewhere where I could get help. I'm still trying to sort the problem out (thanks to redlowrey for his patient help), and I just wanted to ask everyone - on the basis that many of these engines are fundamentally similar - two things: 1) what they would vote as the most common fault and 2) what would be their hot tips for spare(s) to take along.
For my last trip I carried: low pressure and high pressure fuel filters, oil filter, thermostat kit, oil pump kit, fuel pump kit, plugs, two impellors, 4 props, 1 set of prop bushes, water separator, 1 set fuel injector 'o' rings, fuses, oil, WD40, silicone sealant and tools. None of it did me any good recently, and although I'm not sure what the current problem is exactly, I'm thinking of adding a multimeter, an ECM Main relay, a Starter motor relay, and two neutral switches. I'm also going to take a small back-up motor in future, because being stuck in the Amazon for more than a day or so is torture
The only problems I've had (until now) have been: badly seated 'o' rings on the injectors (courtesy of the local service people - idiots), causing a stall in neutral; worn out impellors (twice), causing overheating; and filthy injectors (common problem here - the fuel is execrable), causing uneven running/stallilng.
Any input would be welcome - the Suzuki people here are useless, and no-one seems to be able to give advice on stuff until something goes wrong (like - after the event - "ah yes- that's a common fault - you should always take a spare impellor" etc). Maybe it would be useful for anyone else contemplating long runs and/or venturing into areas where they have to be self-reliant.
