What puller screw remover tool would I use for the various Volvo Penta engines?

As of now, Volvo Penta does not offer a puller screw removal tool for the 21700445 impeller. We can supply you with an aftermarket puller at around $125 which works well with a number of different impellers and has the added aspect that the impeller center does not have to be threaded. Many people use vice grips and just ruin the old impeller. Tool 3843947 puller screws is for the early Volvo Penta diesel engines KAMD32-KAMD44. It is for impellers: 3841697, 21422647 and 2191356.
