Hmm.. well.. I may try a restrictor plate just to see if lower carb size makes a diff. Easy check.

I’m pretty sure my brother was shooting the water jacket on the rear cylinders..

I will check on the alarm function..  I’ve kind of wondered myself whether or not that’s working.. my understanding is that there are two round heat sensors on a v4 that are kind of stuffed into the heads with brown wires maybe ? and what is it that they do they ground out when they reach high temp?  So the buzzer always has 12v to it and the circuit completes if the temp goes high? The.  Beeeeep?

The boat and then motor both use red plug system and I just plugged it in on engine swap and was thinking that the alarms would all line up and work..

I haven’t drilled and tapped the top heads yet…  I may still do it . I found some hydrojet heads in New Hampshire.. but they also seem to come with the trailer of boat two engines and large bill…  not sure I wanr to drive for that.

I’m really kind of interested in what the water flow rate is through the block. I just bought a flow meter online and I’m going to hook it up and see if I can create a graph against the RPM and see if I’m getting a cooling water drop off at higher RPMs
