I recently purchased an older (1987) 19 ft sea Ray Seville. 4.3 alpha 1. Does anyone know what the original prop specs are? 14.5x19 on it now.
The boat may have had an ideal speed prop and some different suggestions based on typical load and activities.
A 19 is a reasonable number. A 21 would be more typical but wouldn't be as good for loads or water sports.
As these boats age prop numbers may become lower.At this point in its life the original prop may not be relative any more.
If you do a lightly loaded test run and get us your hp. and wot rpm and gps speed We can help evaluate your setup.
