Starboard riser hot to the touch

[lrothey]

I have a 2005 Tige Switch V with a 340 Indmar. I noticed hot temps in the 190-200 range so I switched out the thermostat and impeller. After 5 minutes in the boat with light load the temp was right back to 195 degrees. I lifted the cover and the starboard riser was hot to touch while the other side was just warm. Can I get some diagnosis help and advise? Thanks.

If the impeller was not whole when you removed it you'll need to backflush the raw water system and clear any blockages. There's several write ups in the DIY section.

It was in good shape when I removed it but I’ve only owned the boat for 25 motor hours. I’ll try the back flush.

Temp bothers me more then a difference in temp between the risers. Thats normal.
