Plymouth opened their home programme in the Conference League with a comfortable victory over Boston at the St Boniface Arena on Friday evening.
The visitors were no match for an on-form Devils side, who collected seven maximum 5-1 heat wins.
Nicki Glanz and Kyle Hughes were unbeaten by an opponent, while Paul Starke dropped only one point in five rides when he was beaten by Simon Lambert in the final race.
Plymouth skipper Seemond Stephens suffered his only defeat when he picked up some unexpected drive while leading in the first race and laid down his machine to avoid hurtling into the fence.
Lambert, who won three of his six races, was the only Boston rider to provide any genuine opposition, although Darren Rolph suffered a mechanical problem while leading in heat five.
Plymouth:
Seemond Stephens 8+1 (4 rides), Kyle Hughes 11+1 (4), Nicki Glanz 12 (4), Ben Hopwood 7+3 (4), Tom Brown 6+1 (4). Reserves: Jaimie Pickard 5+1 (5), Paul Starke 12+2 (5).
Boston:
Mark Thompson (rider replacement), Darren Rolph 2 (4), Matt Wright 5+1 (5), Simon Lambert 15 (6), Darren Mallett 5+1 (6). Reserves: Adam Lowe 4+1 (4), Ollie Rayson 1 (5).
