Fullback James Tedesco again took control and, with the help of halfback Luke Brooks, set up Sauaso Sue for their first try in the 14th minute.
The Raiders threatened to bite back quickly, but thwarted their chances with a handful of errors.
It was through Boyd they eventually found the points, the 122kg prop using his brute strength to cross in the 27th minute and again just before halftime for a 12-4 lead.
He celebrated his second by throwing the ball at Tedesco, who had been caught napping on the tryline on the back of a penalty.
But that bit of theatre only served to rev Tedesco up after the break, with the No.1 outrunning Sisa Waqa and Jack Wighton on the back of a quick 20m restart for a much-needed try to close the gap to four points.
They briefly regained the lead in the 63rd minute via a converted try via Pat Richards.
But the Raiders made sure it didn't last long with a long-range four-pointer of their own.
Wighton and Hodgson combined to set up skipper Jarrod Croker in an effort that spanned the length of the field.
The Tigers, though, weren't ready to give up, with Brooks scoring in the closing 10 minutes left on the back of more Tedesco magic to seal the victory.
The Raiders next face Manly at home on Sunday afternoon, while the Tigers host Newcastle at Campbelltown on Saturday.
Tigers coach Jason Taylor labelled it a strange game, but was proud of the tenacity his charges showed.
"We had a lot of things go against us and the way the guys kept fighting was really special," he said.
While the joint venture are out of the finals race, the win has pushed them up to 13th on the ladder.
A fortnight ago, they were last.
"We want to keep moving up the ladder, but the fact that we're not in contention is irrelevant," Taylor added.
"Finishing the season in the right fashion and playing some really good football is what we're about.
"It's a credit to the guys the way they're doing that."
The Raiders have now lost eight from 10 matches at home - five of which have been by four points or fewer.
Coach Ricky Stuart put down the defeat to impatience.
"We're a brand new team, we get into tough periods of the game and we're not good enough to close it out - we're too impatient," he said.
"We want to score off every set of six instead of playing percentage football.
"That comes with experience and more time playing with each other."
