Hi Eric, .15HP is not a big deal, depending upon the pump and the impeller. I like to look at two things when replacing a motor: what was on there from the factory and energy efficiency since these little buggers can use a good chunk of your household utility bill.
We often see motors replaced with something that is higher HP than what came on it from the factory. Nothing against your local pool store, but they probably do not stock the variety of motors that we do. Is your current motor the original factory one?
The B847 will use (approximately) 1518 watts and the B854 will use 1840 watts which is 322 more watts. That is 2.5 more kilowatt hours of power per day - times 182 days per year (assuming you close your pool for the winter) that comes out to 456 more kWh of power per year and, at .2 per kWh, that is an additional $91 a year on your power bill.
Let us know what model pump you have (attach pictures of it and any labels on it) and we will be happy to take a second look.
