Thread: Going to look at a used boat

They could have installed that hydrofoil because early shorter Javelin and Stratos boats had weight distribution issues that made some of them difficult to jump onto plane or eventually porpoise. All of the weight was on the stern of mine so I had to move some things around and half-fill the front livewell when fishing with a partner. Check your cavitation plate and be sure that the motor is sitting in the right hole to not be below the keel.

Yea, I'm thinking the boat is little stern heavy, but the plate is not below the keel. That V4 is fairly heavy too. I've read where the foil can actually increase all around performance, including top end, on some setups. So, it may be the best option on this boat.
Also, I just noticed the trim lock pin (or whatever it's called) is in the next to top hole, so that won't help with planing out if the motor isn't tucked all the way in at take off.
Once I get everything dialed in and the boat rigged like I want it, I'm considering modifying it to a 115, but that will be a future project.

Finally got a chance to take the boat out yesterday afternoon for the maiden voyage. Motor fired right up and ran great, although it seemed to idle a little high. Decent chop on the water and fair amount of traffic and the boat handled it well. With 2 of us, GPS top speed was 39.6 mph. It has an aluminum Michigan Wheel 13.25x17 pitch prop on it. I took the foil off last night and moved the trim angle rod to it's lowest setting, so will try it like that next time out.

The boat does not have a tach and there's no hole in the dash, so I'm assuming it never had one. I'm going to install one.
Will the control box have a sending wire to connect a tach? Any pointers on best way to access? The control is behind the wall.

Your control box probably has the three pin plug on it though you may need to be a contortionist to look at it from under the console. Most of the more modern tachs run off of three wires:
Purple Wire: 12v supply for the tachometer.
Gray Wire: Sensor lead for the tachometer.
Black Wire: Ground lead for the tachometer

You can buy the tach harness that will go from your gauge to the control box from any BRP/Evinrude dealer or online. You can splice it up yourself but it's a pain working behind that Javelin side panel so I'd just buy the cable. I had to lay down sideways in the boat to get my head under the console to look at my control box wiring to replace my neutral safety switch and reword some gauges. The gauge is pretty straightforward, find one, tape up your console with painters tape to avoid scratching it up and use a hole saw and a drill to cut her out.

Dutch, I got down and looked and I do not see a plug. I took a photo. Maybe I'm not understanding what I'm looking for.
Do you know where I can find info on this? I've googled and from what I've seen, I should have a 3 prong plug but I don't see one.
There are 2 connectors that include the purple, grey, and black wires.
