Customer Question
Hi I have an...

Hi I have an ex competitor ski boat which was giving me problems.

Mechanic's Assistant: Sometimes boat issues seem like they'll be really complicated, but end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.

Turns out it was the trigger, which mechanic changed .he also however in the process changed the Control Modules. the boat goes well now , but it is 8 klm per hr slower, I think it is revving less at full throttle. Could the previous Control Modules had no rev limiter ?

Mechanic's Assistant: Is there anything else the Marine Mechanic should be aware of?

Not to my knowledge

Customer reply replied 8 months ago
It's about 5700
Marine Mechanic: Jason, Marine Mechanic replied 8 months ago

Were the RPMs higher in the past?

Looks like one of my texts never got to you. I had a mechanic fix the problem of boat not Erving past 1500 rpm it turned out to be the trigger , but he also changed the control modules in an attempt to fix problem, so I thought maybe the ones I had were modified to have no rev limiter and now that he has changed them that could be why it's not Erving out. Boat use to rev to around 6500 rpm cheers
Marine Mechanic: Jason, Marine Mechanic replied 8 months ago
to high, the engine is actually over reving at that RPM. Max RPMS on this engine are 5500 to 6000 RPMS. As long as you are in that window the engine is operating properly. Has your mechanic advised you that*****to high?

Spoke to guys who built original engine and they said it is built for racing, has different heads and all sorts of modifications and is built to rev higher
Marine Mechanic: Jason, Marine Mechanic replied 8 months ago

I don't get into any of that race/custom stuff, I only do factory engines. I will opt out and leave your question open to the community.
