And here is the top and wrap all done up!
Now I just need to find some more time to work out the kinks.

[tnairn]

Had a day to get my best friend and diesel mechanic out to help trouble shoot the issues. We went over to the Harrison river bay to go for a test run where he river has next to no current( I am a little nervous after our long float) we put the boat in the water... it idoled rough, then we went to get up on step and it got worse then went into limp mode. We shut the boat down saw there was two injector related codes and the promblematoc engine speed codes. Cleared the codes got the engine going on the first crank(a big relief). It started up and was misfiring a lot. Put the boat back on the trailer and went home to open up the valve cover and check out the issues. All of the injector hold down bolts were loose and allowing the injectors to lift up under boost. This may have been the main issue for the engine stalling out. ( the engine was assembled by a shop that specializes in VW diesels) I am not impressed as I paid good money to have the engine assembled. But at this point in time it is over a year since the work was done and I don’t see the point in harassing them. We took it to island 22 to see if this fixed anything. Like stated before I am nervous about the engine stalling so we just left the boat on the trailer for something to push against. Ran the engine up to 2500 and back to idol then up and down a few time, it just purred and was so smooth no missfires or codes.
Maybe one night this week we will get it out for some more testing and see if everything is good.

This is one of the best build threads I have seen on this site. Really hope it starts running good for ya .....just curious, since you did most of the custom stuff yourself and Bean built the hull, what did High Caliber do?

[tnairn]

I believe it is high caliber design built by bean and the tunnel is a high caliber thing too.

A lot of the nice wake boats have fancy trees at the Front of the trailer with steps, here is one of the two steps I am planning for the bow of the trailer, this is what I got made up on my breaks at work today.

[tnairn]

I got the boat out Sunday, I was able to get it on plane and going without any stalling issues or codes, that was a big suscess. But it needs tuning as I am playing with the upper end of my Exhaust gas temperature range, I am going to work with my tuning company and do a bunch of data logging to see if we can get the boost up and temps down.
If that still does not get it to a safe temp range at full throttle for a decent amount of time I will strip down the intake and exhaust manifolds water jacket what I can on The exhaust and add more heat shields for the intake manifold. That is the only down fall for this engine is that they share the same side of the engine.

What egt's are you getting and what do you consider safe for this engine? I have an ALH and have been having a hard time getting power so I am changing things. My understanding is that anything less than 1200 should be safe.

1200 or less is my feeling safe zone, I was told by my tuner with the turbo I have up to 1450 is sustainable and 1750 bursts but I don’t know how I feel about that.

Your pistons melt at just over 1200°, the hotter your egt the faster they will heat soak to that point. I'm sure you know all that, just pointing out the turbo isn't the onlt thing to worry about...

[riverboater]

That is the basic issue with asking lots from a small package. What good is a boat that can not run at full throttle for an hour when need be.

[viking]

Lots of things can't run at full throttle for very long. Like cheetahs, for example.

You have never ran anything with an LSA

Viking ... wow. That's awesome.

Yes, the umbilical cord from the tanker is a tripping hazard for the floaters, and tankers are too wide to safely fly the canyons. Logistical nightmare!
