Hey everyone, I own two hulls, and I have nagging problems on each boat's engines:
  • My 200 HPDI will only start when the engine is cold. I can still start it by removing the engine cover and jumping the solenoid with a piece of wire. I suspect the Solenoid is faulty (I changed the ignition switch, persists, checked for bad ground, etc and the problem still persists).
  • The other is 50 HP 4-Stroke Yamaha, and let's say we had a bit of an accident with crossed wires and the engine is now dead.
Anyway, I have been told that Salvador Mitre and Jesus Salas are very good at electrical problems and I have tried to get them to come over and check my motors out but they are extremely busy. Wanted to know who else could check out my engines? Star Marine? Luis Shop? Someone else?

I have never taken an outboard to Luis but I believe him to be an honest man and there is a lot of collective knowledge in his shop. HPDI motors have been out a long time, so I am sure he has worked on them before.


With the cold start issue, it could be there is a sensor that is intended to prevent starting when the engine has overheated that is malfunctioning. Possibly it prevents the solenoid from operating and you are simply bypassing it. 

In any event, TRACE EVERY GROUND WIRE AND MAKE SURE THERE IS NO CORROSION. Trace it all the way back to the battery ground, engine ground, etc. Weak grounds can cause lots of problems, when DC electricity can't get back to its ground. It costs you nothing to do this yourself, but time.

Also make sure the wiring harness is not crimped in any location.


Does it run good when you DO get it running?


A Google search on "HPDI electrical problems" reveals a lot of information. Read through the posts, especially the ones on The Hull Truth, as that site has been around a long time and has many members.

I did read one post that talked about Yamaha diagnostic software being available on e-bay for under 100.00US. If you plan on keeping that engine, it might be worth investing in it.

Alfredo, the heavy set suzuki electrician at Star Marine is a step up from anyone I have ever used in 30 years in SC for diagnostics.

Yes the engine runs perfect once it starts, very powerful and great acceleration, it's on a 21 foot Contender. Has never stalled, sputtered or backfired in the 3 years I've owned it . The starting problem began sporadically.
Will check the grounding. Yes I check the Hull Truth regularly as well, they said it sounds like the Solenoid is going bad. Anyway thanks for the suggestions. I need to fix this annoyance and be off to the races!
Jeff, will look the guy up, thanks for your advice!

Luis is very good, if he or Elvis doesn't know first hand, they'll research. I've had a little Mercury 20 over there before for a complete check up. I have a 200 Mariner there now for a good going over. I would not hesitate asking Luis or taking it over there. Ron

Problem is fixed. Alan and Alfredo from Star Marine took care of it, it was a corroded harness inside the engine.

TONY ABQ, I have heard and know of 10 stories about H for each one I have heard about Luis. Usually, it's all about money; one is cheap, one is not. One is a good friend, honorable, knowledgeable, and I would trust with a key to my house and car. I trusted Luis with everything on my boat for 7 years; I can afford it and believe in value over price.
It is cheaper when you use a box of decent wine as a "propina"!
Saludos Luis!
