Ben,
I had a similar issue on a 18hp Fastwin once. It would pump great at idle, but run hot. My problem was a bunch of crap in the water intake screen behind the prop. Water would come into the pump area through the bypass cover, but not through the screen. Easy fix for me. Hope yours is something simple too.

If memory serves me well look on the exhaust snoot in front. You will see a small round cavity in front. It has a screen or should have one to filter out the weeds. Be very careful taking out the exhaust bolts. They are good at breaking because they get stuck. If you have a small torch heat the area where the screws go into the block. Also give the screw heads a good hard tap, this helps break the screws loose. Be patient please. It has an inner & outer plates. The inner plate keeps the exhaust gasses going down into the leg to the outlet. The next plate is the cover you see. The pump sends water up the waterpipe & into the exhaust cover at the bottom & into the water jacket around the cylinders then out the motor on the bottom. This water outlet now cools the hot exhaust gasses & exits the outboard. When you have the covers off stick a small screwdriver into the water flow cavities to see if the passages are clear & will flow thru the motor. The cylinders water jackets hold crud on the aluminum & restrict cooling. Scrape off all you can before digging into the aluminum. I bet you get mucho off. Put a piece of wet & dry tapped to a flat surface like thick glass do a figure 8 with the part until it is clean & no pits. If you have pits use a gasket sealer to not have any leaks, use it very lightly but fully. If you take your time with the new gaskets & surfacing all your leaks will go away. Once you get the inner stainless steel cover very clean, hold it up to some light & look for pin holes in the metal. If the water gets inside the motor it will destroy the rods, crankshaft & rings with rust so be so careful replacing the exhaust covers & gaskets please.
I hope this helps you get back on the water soon!!!

Thanks for your reply. I wonder if my screen may have gotten blocked or partially blocked with weeds while I was running on the lake. I checked the intake screen and there is nothing on it now, but that may have been on there until I rowed back to the dock. Either way, it has to come apart now.

Thank you very much for all your help and advice on this. I will certainly be careful and take my time, especially with the exhaust screws. I’m sure they are like any other screws that hold exhaust components together. They like to get stuck in a big way. I’m going to try to get back after this thing as soon as possible. I want to make sure the internals don’t rust just in case it has already gotten water in it from the leaks. Worst case, I do have a parts motor with another complete powerhead that seems to be in good shape. Hopefully I will be able to get this one back up and going without using the other powerhead.I’ll post the progress as I go. Unfortunately it may not be as quickly as I would like. I also have a tendency to have more than a few projects going great at once so any given one doesn’t always go as quickly as it should.
Thanks Again,

June 1, 2016 at 2:37 pm #37541I need to get new gaskets for this motor. What is the reason recommended source for gaskets for this motor? This is one of my older motors. Most of them I don’t have any trouble finding gaskets for but this one is a little more challenging. I still have a new set of base gaskets for this one, but I need a head gasket and the exhaust cover gaskets. I’m sure I can find some but recommendations are appreciated. I’m sure I’ll have fun when I get into my LT-38.
Thanks,

June 1, 2016 at 4:34 pm #37550marineengine is a good company. Prices do seem high, but hey, it’s a boat, right? Seriouisly, there are several clubmembers that have a stock of parts for sale. Perhaps one of them will see this and send you a PM
June 1, 2016 at 4:47 pm #37552Hi Frank,
Thanks for the reply. I do use marineengine.com quite a bit for parts. I like doing business with them and they ship really quickly. I have had a number of instances where some parts from them are a really good price and one or two will be really high. Most of the time it eveno out though by the time I pay shipping get from someplace else. I don’t have any good local parts suppliers that have hours that allow me to use them. Otherwise, unless the prices are way off, I’m all about supporting the local guys. All about supporting club members too.
Thanks Again,

I’ll get in touch with Dan Gano. I have not bought anything from Dan yet and I didn’t know what all he has. I checked out his site before and thought about trying him though. I’ll give him a go.
